Maxtor DiamondMax 160 GB Plus 9 Review


Date: 25.06.2003 




    The internet is available to pretty much everyone these days and the number of people succumbing to the “broadband bug” is growing at an unimaginable rate. Kids may come up with many elaborate excuses to get their way with their parents, such as “I need it for school” or “Everyone else has it, why can’t we?”, but in the end we all know the world of peer-to-peer sharing is not oblivious to kids these days. This isn’t to say its just kids doing these things… ;-)

    I’m not going to turn this into a rant of some sort, or an editorial stating which side of the issue I am on. I’m merely telling you what you’ve most likely already heard or come across before. There’s actually thousands of websites and many tools users can utilize to acquire this material, but I’m not going to disclose nor comment on these because I don’t feel like having a law suit filed against me right now...

    The point is, hard drives these days are being filled up like never before. I’m just here to review the storage; however you make use of it is up to you. On that note, the amount of storage a single computer can have is enormous. At the present time, hard drives can be found up to 300 GB in size. Not only that, you can easily install multiple hard drives in a single system. The amount of storage you can accumulate in your computer nowadays really only depends on how fat your wallet is.

The Package:

    The packages I received were OEM style white box with some courier information on it. Nothing really special, no flashy packaging, but who needs that right? We’re more interested in what is inside the packages. The only delay I encountered while opening them up was when I couldn’t find anything sharp enough to pierce through the packing tape. That was quickly solved and I was well on my way.

    In the first package, I found a box containing the PCI ATA adapter card. I’ll talk more about that later in the review. In the other box, much to my surprise, I stared at some packing peanuts and another box. After taking out the smaller box, and cleaning up the mess I made with those peanuts. Those Russian dolls came to mind as I started to wonder whether there would be another box inside this box. That thought was quickly dispelled as inside this box I found some foam. Cut out inside the foam, was a neat little holding cell for the hard drive nicely packed in an ESD bag. Nice packaging job, that’s for sure!

(1) PIP…err…BIB (2) Holding cell

The Materials:

    Enough of my rambling, let’s get to the actual goods that I'll be shoeing you today...

  Ultra ATA/133 PCI Adapter Card:

    First up for bids…or no not for bids, for showing, is the PCI adapter card. It looks like watching “The Price is Right” on those boring weekday mornings has to stop… Anyways, let’s check out the unit itself.

(3) The box (4) Open Sesame!



    As you can see, included was pretty much everything you will need. Inside the PCI adapter box I found a “how to” guide, utilities/driver CD, the card itself, and even an ATA133 IDE cable. Only thing I needed to provide on my own was the needed screws to mount the drive. For those of you who don’t know, the “Ultra ATA/133” part means that it supports a max throughput of 133MB/sec on ATA133 devices.

(5) Card top (6) Card bottom (7) Top close up


(8) Channels close up (9) Controller chip


    Seen above is the adapter card in all its glory. There is no need to memorize which channel is which, as it’s clearly labeled for you. Something I should mention here is that you are not only limited to attaching hard drives to the adapter. Any IDE device can be attached and it will function just like how it would if it were attached to the motherboard. That’s the whole point of having these things, so you can more devices as necessary.

    Seen in the last photo is the controller chip, which pretty much just controls the transfer between the device and the PCI bus. Maxtor used a controller chip manufactured by Promise Technology, INC on the card, as you can see.

  DiamondMax Plus 9 160GB ATA/133:

    The hard drive is the 2MB cache model for those of you who were wondering. It is also available in an 8 meg cache ATA/133 model, and even Serial ATA models.

  Above is the drive in an assortment of angles. What more can I say other than it looks exactly like any other Maxtor hard drive. More specifics for the drive can be had here, as well as info on the whole DiamondMax line. I will put the important ones pertinent to this drive below for you. Remember to arm yourself with the latest version of Adobe Acrobat Reader, which can be had here, for no cost at all.

Only 127 GB of space shows up after formatting?:

    Maxtor says in order to have large drives work, you NEED Windows 2000 or XP. Due to the size of this drive, 160GB, it is NOT as easy as plugging it in and having it work correctly. What I mean is that there is both a BIOS and Windows limitation on the size of the drives they will recognize. If you just plug the drive in and go to windows to format, it will only format to a max capacity of 127GB. It’s not because the formatting stops at the 127GB mark, it’s because that is the size windows will recognize. One possible work around, I’ve heard, is if you update Windows XP to SP1, it will recognize large drives without problems. I haven’t done this myself, so I’m not sure if this works or not. If someone would like to let me know if this does work, feel free to shoot me an email.

    Another fix, which is a sure thing as this is what I did, is to download MaxBlast 3 from Maxtor’s website. It can be found here. All you need to do is download the utility, make sure you have a 3.5” floppy drive with a formatted disk inside, and run the utility. It will do its thing and make the floppy bootable. Next, restart your computer with the floppy inside the floppy drive and attach the hard drive. Let it boot from the floppy, select that you want to run MaxBlast from the floppy (F) and it will start-up. It will automatically detect the large drive, and ask if you want to prepare the drive for use on your system. Click “Yes”. Next it will ask you if you want a basic setup or advanced setup. If any of you have formatted a drive on a Windows 2000/XP system through Disk Management, the options are fairly similar in the advanced setup. For those of you who haven’t done that before, I suggest you do nothing but keep clicking “next” until you are done :-) After you are done, it will format the drive and restart. Upon restarting, there’s nothing more to be done. Go to “My Computer” and the drive is formatted to its proper capacity. Now you can go do your thing and do whatever you wish with about 160GB of storage space. Remember, 160GB as deemed by the manufacturer does not mean 160GB will show up in “My Computer”. That’s normal, and is due to the fact that a gigabyte is based on the metric system. For example, a gigabyte is 1,000,000,000 bytes. Your PC uses the binary system. The same kind of situation that exists in the USA. They refuse to use metric measurements that the rest of the world uses. Anyway, in the binary system, a gigabyte is 1,073,741,824 bytes. Hence, you do lose space when you format your drive.

    For older systems that experience problems while booting with larger drives, keep reading. To overcome such BIOS limitations there is a fix. For this the knowledge base at Maxtor is actually quite good. This link explains the process much better than I would be able to, so check it out. More searching yields more help if needed. :-)

    There is a “Cap Limit” jumper on the back of this drive, which successfully gets the bios to detect the drive as 32GB. That would alleviate the problem faced by some with older motherboards as mentioned above, however the problem is that the operating system also detects it as 32GB. Maxtor’s knowledge base says that if you are using Windows 2000/XP, you should not use the Cap Limit jumper. Instead you should use the above MaxBlast method. Even if you are using a previous version of Windows, I assume this still holds true.


Testing information:

HD Speed
Quick Bench 1.1
SiSoftware Sandra 2003



    Performance will be compared between my own 60GB drive as well as the 160GB drive. The 60GB drive was configured as the master device on IDE channel 1 and the 160GB drive was also configured as the master device on IDE channel 2 when the motherboard controller was used. This was also the case when the PCI controller was used. There were no other devices on either channel at the time of testing. The average of three runs is recorded below in each scenario.

  HD Tach 2.61


(16) Reading performance (17)Read burst rate


(18) Random access

    From the results above it can be seen that the hard drive not only did well when compared between the motherboard and PCI controller, but overall performance was quite commendable as well. The differences between the motherboard and PCI controller is quite small and likely won’t be noticed. One thing to remember while reading the above benchmark results is that the 160GB drive had to maintain the speed over an additional 100GB.

   SiSoftware Sandra 2003

(19) Look at that void!

  Time for everyone’s favorite benchmark, Sandra! Even though it is purely synthetic, it’s made itself quite a name in the reviewing business. The results are pretty straight forward, with not much to explain. The difference between the two drives is shown here fairly outright, with the 160GB again in the lead.



  HD Speed


(20) HD Speed results



    That’s quite the version number they got there… Once again, the performance is more or less neck in neck. At this point I’m about ready to call it even. But just to be sure, let’s take a couple more programs for a whirl.



  Quick Bench 1.1


(21) Quick Bench results



    Again, not much of a difference between performance with respect to the motherboard controller and the PCI adapter, but the drive seems to be doing pretty well. Next up is the last program used to put the hard drive through its paces.

Atto Disk Benchmark 2.02

(22) Atto Motherboard Read results (23) Atto Motherboard Write results


(24) Atto PCI Read results (25) Atto PCI Read results


    According to the Atto disk benchmark results from above, it’s quite evident that there is little difference between the motherboard controller and the PCI controller. The disk performed quite nicely as well, reaching max speeds of about 60,000 KB/s. Overall I am quite impressed.


    In the end, the performance difference I found between the PCI adapter and the motherboard controller was negligible. A few more or less MB/s here and there isn’t anything to worry about, nor to care about. The drive itself benched quite nicely, and I am quite pleased with the performance. When compared against the 60GB drive, the 160GB fared quite well. As the saying goes, you win some and you lose some. The noise level was also very reasonable, which is a big plus for those of you who are massively inclined towards having the quietest computer ever.


  • huge capacity

  • fairly fast speed for an IDE device

  • quiet

  • affordable - ~$125.00 USD on pricewatch


  • ATA 133 card does hamper performance slightly

“Quiet and high performance. What more do you want?”


Maxtor DiamondMax Plus 9 160GB S-ATA Drive Review

Date: 12.04.2003

Introduction :

Maxtor, a company founded in 1982 with over 12,500 employees world wide is one of the leading storage manufacturers in the world today, with its multi-billion dollar revenues growing every year as Maxtor gains market share in the very crowded and competitive world of the home and enterprise storage markets. Maxtor was one of the chief promoters of the Serial ATA Working Group, along side Dell, Intel, and Seagate among others. Seagate beat Maxtor to the punch by releasing the first retail Serial ATA hard drive, which is widely available right now, but as we saw in testing the new drives, there really was no performance gain going from the Parallel ATA to the Serial ATA interface. The advantages of the Serial ATA interface include thing and easy to maneuver data and power cables, and of course the maximum throughput of the drives is increased to 150mb/s, which is of course theoretical as current ATA drives never reach those speeds.

Maxtor taking a little more time with their Serial ATA based hard drives has decided to implement some unique features in their DiamondMax Plus 9 Serial ATA drives, including a 4 pin Molex power connector along with a Serial ATA power connector. This is primarily done because that Serial ATA power cable converters are relatively hard to find, and when found cost on average $8-12. The standard 4 pin Molex power connector does not really cause an airflow problem due to its small size, so this 4 pin connection will be a welcome addition to many users interested in a Serial ATA hard drive. Additionally, most motherboard manufacturers do not include a Serial ATA power connector with their motherboards, making even more sense as to why the 4 pin Molex power connection is on the Maxtor DiamondMax Plus 9 160gb Serial ATA Hard Drive.

We've already seen how SATA drives compare to ATA drives in previous reviews, so lets take a look at how the two newest SATA drives stack up against each other, the Maxtor DiamondMax Plus 9 160gb Serial ATA Hard Drive and the Seagate Barracuda V 120gb Serial ATA Hard Drive.

Specification :

Interface Serial ATA
Space 160 Gbytes
Internal Transfer Rate 570 Mbits/sec
Max. External Transfer Rate 150 Mbytes/sec
Average Seek Time 9.4 ms
Spindle Speed 7200 RPM
Discs/Heads 2/4
Bytes Per Sector 512
Power Requirements +12 VDC +/-10% (amps typ operating)
Operating Temperature 0 to 60 °C
Dimensions (hxwxd) 26.1 x 101.85 x 146.56 mm
Cache 8mb

Drive Close Look:

As you can see from the top view of the drive, the Maxtor DiamondMax Plus 9 160gb Serial ATA Hard Drive looks exactly the same as a standard Parallel ATA hard drive, using the same form factor and labeling as the rest of the Maxtor DiamondMax Plus 9 family.


Maxtor has not decided to do anything drastic with the overall design of Maxtor DiamondMax Plus 9 160gb Serial ATA drive, exposing the drive's PCB when turned over.


When turned onto the card's side you see the three standard screw holes for mounting the drive into your enclosure.


Now when looking at the back of the card we can see the features that set this drive apart from any other ATA drive currently on the market. You can see the Serial ATA power connector (larger) and the Serial ATA data connector (smaller) to the left of the drive, then moving right you of course have the drive's jumpers, and then at the far right we have the 4 pin Molex power connector that plugs easily into your power supply.

It's most likely going to be a while until we see Serial ATA power cables imbedded with power supplies, so once again I must say that this 4 pin power connection is a very welcome addition to the Maxtor DiamondMax Plus 9 Serial ATA Hard Drive.


And once again you can see the drive in all its glory, one thing I'd like to mention is that because of the drive's FDB (fluid dynamic bearing) motors, the operation is among the quietest of any hard drive tested, and the drive also runs relatively cool for a 7200rpm drive, not requiring any external cooling like some of the 10,000rpm SCSI drives we've tested.

Benchmarks Settings

  • HD Tach 2.61
  • SiSoft Sandra 2003
  • Ziff Davis Winbench 99

HD Tach 2.61:

HD Tach is a low level, physical performance hard drive test for Windows. Although it is a little dated, it provides a lot of good information in regards to hard drive performance particularly read speed and seektime.

Random access is the true measure of seek speed, as it is the time it really takes to read data, not just the time it takes to move the head to the proper cylinder. To calculate access time the software must read a single sector off of the hard drive and by reading a sector the drive can not respond to the command until the sector is available, so rotational latency + seek time = access time.

Our Random Access Time results were very simple, the Maxtor DiamondMax Plus 9 160gb Serial ATA Hard Drive outperformed the Seagate Barracuda V 120gb SATA drive by .3ms, a substantial margin when we're looking at hard drive speeds.

The maximum read speed is of course the maximum read speed achieved throughout the HD Tach 2.61 testing, and we can see the Maxtor DiamondMax Plus 9 160gb Serial ATA drive actually having a maximum read speed thats 16mb/s faster than the Seagate Barracuda V's. Once again, a very substantial difference in speed between both drives.

The HD Tach 2.61 minimum read speed scores come in favor of the Seagate Barracuda V, whose minimum read speed is actually 6mb/s faster than the Maxtor DiamondMax Plus 9's.

However, when we move onto the average read speed portion of the benchmark, Maxtor once again takes the performance crown as it's average read speed is just under 11mb/s faster than the Seagate Barracuda V's.

SiSoft Sandra 2003:

SiSoft Sandra 2003 is the newest version of the very popular benchmarking suite Sandra, a program filled with benchmarks that test your CPU, memory, network, cd-rom, and of course hard drive. The hard drive is tested through the file system benchmark, and is another good indication of raw drive performance. Lets take a look at how the two SATA drives faired in the test.

Like we've seen throughout our tests, the Maxtor once again outperforms the Seagate SATA drive by once again, a substantial amount. This time around the DiamondMax Plus 9 scored just under 8mb/s faster than the Barracuda V.

Ziff Davis Winbench 99:

Ziff Davis' Winbench 99 is one of the older benchmarking suites still widely used today by many to test the performance of their drives in various applications, such as business and high end applications. The latest version is version 2.0, but even though the program is dated, it provides very relevant and accurate information about hard drive performance using the various Disk Winmark's provided in the suite.


In our Business Disk Winmark tests you can see the Maxtor SATA drive once again score significantly higher than the Seagate Barracuda V SATA drive, outperforming the Seagate by a score of 2600 kb/s.

Concluding our benchmarks is the High End Disk Winmark from Winbench 99, and once again we see the Maxtor DiamondMax Plus 9 160gb Serial ATA Hard Drive taking the Seagate Barracuda V 120gb Serial ATA drive to school, this time outperforming the Seagate by 12700 kb/s.


A few months ago, people were very skeptical about Maxtor's line of Serial ATA hard drives, primarily due to the fact that the line was delayed and no reasons were given. This delay opened up a time window for Seagate to release their line of Serial ATA hard drives, the Barracuda V's. However, the Barracuda V performance was basically on par with the current parallel ATA drives around and did not offer too much in terms of performance in any benchmark we've tested with. This led many people to forgo the Serial ATA standard, even though many of their motherboard supported it, as parallel ATA was clearly equally if not faster in many cases, and cost less

My, what difference a few months can make. With Maxtor finally introducing their first SATA drives, we can see the delay was worth it, as they have come out with a truly unique SATA hard drive solution. For starters, they have foreseen that many users would like to use their standard 4 pin Mo-lex power supply connection on the drive, and built that right into the card. Using their fluid dynamic bearing motors they have released a drive that is not only among the quietest 7200rpm drives on the market, but is also superior to other SATA drives on the market in terms of performance.

We saw the Maxtor DiamondMax Plus 9 160gb Serial ATA Hard Drive actually score up to 30% faster than the Seagate Barracuda V 120gb Serial ATA Hard Drive, essentially killing it in every benchmark except for HD Tach 2.61's minimum read speed benchmark.

The question to you now is if you should buy a Serial ATA drive if you have a motherboard that supports it, and now the answer is definitely a YES! The newest line of Maxtor SATA drives is definitely a worthy upgrade for any enthusiast or user looking for a new hard drive, and finally with improved speeds the Maxtor DiamondMax Plus 9 series of hard drives is definitely the line of drives to buy from.

With Western Digital soon entering the SATA market along with a new generation of Seagate SATA drives in the next few months, the SATA standard will only get stronger and it will be interesting to see how long Maxtor is able to keep the Serial ATA performance crown to itself.

VR-Zone Rating : 85 VRMarks!

Maxtor DiamondMax Plus 9 160GB
was given an Editor's Choice SILVER Award!

Maxtor DiamondMax Plus 9 6Y160M0

If you are looking for a high-capacity hard drive with the best performance around, Maxtor’s Diamond Plus 9 160GB SATA drive is your final destination. With its Serial ATA interface that offers 150 MB/sec transfer speeds and a large 8MB buffer, this drive easily stands above the rest earning our coveted Editors Choice Award with a perfect 10 score.


True SATA performance

If you have been following reviews which cover various SATA hard drives, then you know that there are plenty of drives on the market which are not living up to the performance which Serial ATA 150 is promising. Maxtor's 6Y160M0 on the other hand proves that speeds of 150 MB/sec can be reached and thus gives us faith that the SATA spec was created in the name of better performance.


The 6Y160M0 Diamond Max Plus 9 drive we received from Maxtor was not in the retail packaging which consumers would be familiar with from retailers, rather is packaged in white box OEM fashion. This means that no documentation, cables or drivers where included. So this review will be focusing strictly on the drives reliability and performance.


If you are buying this drive as a white box product make sure to download Maxtor’s Maxblast program for formatting and partitioning the drive. Those buying the retail version of this drive will get a copy included on a bootable CD. If you have an operating system older than Windows XP with service pack 1 or Windows 2000 with the latest service pack, then you will most likely have to partition this drive into separate partitions. This is because Windows operating systems other than what were mentioned will not support drives larger than 137GB (or smaller depending on which operating system you have).


Our test system consists of the following:


  • AMD AthlonXP 1700+ with stock heat sink/fan
  • Abit AT7MAX2 motherboard
  • 512mb of PC2700 Crucial DDR Memory
  • Leadtek Geforce 4 MX video card
  • Plextor 504A DVD Writer
  • Enermax 350W whisper power supply


The Maxtor 6Y160M0 drive proved to be incredibly fast in our tests.  In our Winbench99 tests the 6Y160M0 showed very fast sustained transfer rates making this an excellent drive for audio and video storage, where you need to maintain consistant substantial transfer rates. Another good sign was that our HD Tach  2.61 tests rated this Maxtor drive better than any other drive we have tested making this an excellent choice for everyday computing tasks, no doubt due to the massive 8MB buffer. The 6Y160M0 tested 11.4ms access time in Winbench99 which is very impressive. CPU utilization is about 11.5ms which is average.


Hitting it hard

The Maxtor 6Y160M0 promises to be reliable and is shock rated to a hefty 60G while operating and an outstanding 300G while turned off. The 6Y160MO is also very quiet although not as quiet as Seagate’s Serial ATA drives, but performance is what matters to most and that is what the Maxtor Diamond Plus series is all about. Overclockers will want to watch out for the amount of heat put off by the 6Y160M0 as it puts off more heat than most drives.


Maxtors warranty includes replacement in 2 business days, 24-hour online and e-mail support and phone support Monday through Friday.


Drive Specifications (these are the numbers given to us by Maxtor and may vary):

Maxtor 6Y160M0 Specification


Measured in kilobytes per second; longer bars indicate better performance

Winbench 99 Benchmarks

Measured in megabytes per second; longer bars indicate better performance
HD Tach 2.61 Benchmarks

You can see how much of a performance increase the Maxtor DiamondMax Plus 9 6Y160M) drive holds over the Maxtor DiamondMax D540X 160Gb drive. Keep in mind that the D540X drive has a speed of 5400RPM compared to the 7200RPM speed of the 6Y160M0 Drive. The D540X also has a 2mb buffer and ATA 100 transfer speeds. Both the D540X and 6Y160M0 drives had read burst speeds off the chart, over 80 megabytes per second.




The 6Y160M0 currently offers the fastest sustained throughput of any 160GB drive we have tested with good seek times. If you are looking for a fast and reliable storage solution, the Maxtor 6Y160M0 offers the best solution currently on the market.


Maxtor's DiamondMax Plus 9 Serial ATA Drive
Serial ATA Drives Mature

Date: 20.03.2003

Our first look at a Serial ATA drive, quite frankly, was a little less than inspiring.  That is to say that, even though the SATA 150 standard offers a higher bandwidth interface and those tidy, thin little cables,  the performance of the first drive to hit our bench, a Seagate Barracuda V, was about on par with the average ATA100 or ATA133 drive on the market.  However, as we all know, in this game of technological leapfrog, it doesn't always pay to be too early to adopt the latest and greatest architecture, for your own personal use.  Many times, it pays to sit on the sidelines, as OEMs and Manufacturers iron out the kinks in their designs and tweak them for optimal performance and stability.  What may not be obvious to the average consumer, regarding Serial ATA, is that drive manufacturers have to tune their drive circuitry to efficiently and robustly take advantage of the higher bandwidth associated with Serial ATA, as well as its radically different I/O structure.  As we've seen many times before, anytime a groundbreaking architecture is introduced to the PC, you can be sure it's going to take some time for the product to reach its full potential.

A couple of months have passed since we spent quality time with Seagate's first SATA offering.  Today, Maxtor steps up to the plate with their Diamond Max Plus 9 entry into the SATA market.  Maxtor has had the luxury of the past three months, to let their first SATA driven Desktop/Workstation drive mature and evolve.  The DiamondMax lineage has always ranked well in performance and reliability but perhaps not in the upper echelon with Western Digital's top end 7200 RPM ATA100 product.  On the other hand, SATA technology brings in a new frontier. 

Today, we've pitted this new DiamonMax Plus 9 Serial ATA drive from Maxtor, up against a Western Digital Caviar Special Edition drive and a Seagate Barracuda V SATA drive as well.  First let's take a look at the Diamond Max Plus 9 and show you what it's made of.

Generation 1 Serial ATA Technology - 150MB/Sec

Once again, looking at the specs of this new Maxtor SATA drive, reveals nothing too surprising or impressive, in all honesty.  On the other hand, this drive does boast some of the latest compliments and enhancements to ATA drive technology, including an 8MB Buffer Cache and of course its 7200 RPM spindle speed.  What is perhaps more impressive than at first glance, is Maxtor's "FDB" Motor technology that this drive is built on.  "Fluid Dynamic Bearing" is what the acronym stands for and it's safe to say that it delivers some of the quietest 7200 RPM operation we've heard in a drive to date.  There is very little, if any spindle whine, as we've heard for so long from many an IBM or WD drive and the read/write head chatter is also much improved over the Seagate Barracuda V SATA drive, we reviewed back in January. 



The DiamondMax Plus 9 SATA drive is constructed well and fairly stout for a mainstream desktop unit.  There are no breather holes on the casing of these drives, so you need not be concerned with accidentally covering one up during installation.  The drive does get fairly warm during operation but no more so than the average 7200 RPM unit.  The circuit board is exposed on the underside and you'll note this Marvell chip provides a bridging functionality for the SATA interface.  It seems as though this drive isn't a "native" Serial ATA drive per se but rather a parallel ATA drive, that has been converted to interface to SATA.  We've got mixed emotions about this.  On one hand, the serial to parallel conversion, with Marvell's Phy chip, is a well known high speed, high quality implementation.  Marvell easily has some of the best SERDES (Serializer/Deserializer) technology in the business.  This setup also allows Maxtor to configure base units and then set them up for either standard ATA or Serial ATA, depending on demand. 

On the other hand, what are we missing by not utilizing a true serial implementation from the main controller ASIC, on back to the actual link level?  Frankly, we're not sure if there is a tangible benefit with a "native" SATA implementation or even if one exists at this point in time.  In addition, as you'll see in the following pages, this performance of this drive shows no limitation, that one could attribute to the parallel to serial conversion, that is done on board. 

Setup  And Preliminary Testing

We won't get into to the actual physical installation of this drive.  If you are familiar at all, with a basic 5 1/4" drive installation, you'll have zero issues.  However, obviously Serial ATA Cables are significantly less bulky, as compared to their Parallel ATA counterparts.  If you're a cabling neat freak (and we have a few of those types on the HH Team for sure... BigWop), once you go SATA, you'll never go back.  In addition, there are no Master/Slave jumpers on a SATA drive to concern yourself with, since it is a point to point connection and only one drive is connected on a given channel.

Any Sales or Marketing type worth their salt, would understand the basic motto, "delight the customer".  Let's just say the Engineers and Marketing Managers at Maxtor had their collective thinking-caps on, when they decided to incorporate a standard 4 pin Molex type power connector on the backside of this new drive.  We were perfectly delighted to see this one simple addition.  It's the little things that make a difference.

Cable Connections and Installation


In the left hand shot above, you'll note the two traditional types of standard Serial ATA cabling, that are used to connect a SATA drive to a system.  The 4 pin power converter cable and the thin gray or red colored data cable.  However, with the DiamondMax Plus 9 SATA drive, you don't need the SATA power cable converter, since you can simply plug a standard 4 pin Molex type connector into the back of the drive.  This simplifies cabling a little more and since most Motherboard OEMs don't pack the SATA Power Cables into a bundle, opting to only include the Data cable, you would have to purchase one separately.  Not so with the DiamondMax Plus 9.  This does again hint that perhaps this is a PATA drive, in SATA clothing but who really cares?  Regardless, nice work Maxtor...  Thanks for thinking of the consumer and the huge install base of SATA power cable FREE systems out there.

Test Setup and Methodology

In the following series of tests, we used identical peripheral components, an Asus P4G8X Granite Bay based motherboard, with a Silicon Image SATA RAID controller.  Our system was configured to run at a stock speed of 2.8GHz on the processor, with aggressive memory timings and 2 256MB sticks of Kingston HyperX DDR DRAM memory.

We then installed WinXP with the respective SATA controller drivers, on a clean formatted 60 Gig ATA 100 drive.  In the case of the SATA testing, we attached either one or two of the Maxtor DiamondMax Plus 9 SATA drives or two of the Seagate Barracuda drives on the SATA ports, in either single SATA150 or RAID 0 mode.  With the ATA100 testing, we simply attached another Western Digital Special Edition, 120 Gig drive on the secondary Intel ICH4 IDE channel.

All Test Drives in these benchmarks were partitioned with NTFS at their fullest capacity, formatted and left completely blank.  Testing and benchmarking software was run off the primary boot drive and directed to test either the blank SATA drives or the blank ATA100 drive.

Sandra Hard Drive Benchmarks

Sandra's Hard Drive test is a decent measure of "burstable" performance, with reads and writes on a given drive.  It's certainly not a "real world" benchmark in this regard but it does give you a feel for file and application load time performance.

Barracuda V

This is more of a quick sanity check type of test for us here in the HotHardware Lab.  Although it is hard to directly correlate the metrics above to real-world performance, you definitely can get a feel for how a given drive will measure up under heavy load and in actual application performance.  Simply put, whether we're looking at the single SATA 150 configuration or an impressive SATA RAID 0 array, this new Maxtor DiamondMax Plus 9 SATA drive pushed out the best score in this test, we have seen to date, for a Desktop ATA drive.  The 60K number in the DiamondMax Plus 9 RAID 0 setup, specifically puts the reference ATA100, 8MB Cache, RAID 0 Array configuration, to shame in this test.  Furthermore, this Maxtor drive also handily puts down the Seagate Barracuda V, in either single or RAID 0 configuration.  Is this an indication of things to come?  Read on my friend.


Hard Drive Tach and Winbench Disk Winmarks

In our next test, we used HD Tach mostly as a read performance benchmark.  While write performance is obviously an area of concern, especially within video and audio recording and editing applications, read performance on a given drive is paramount to the over all "feel" of how responsive your system is.

HD Tach reports that the DiamondMax Plus 9 SATA drive is faster than both the Barracuda V and the Western Digital Special Edition ATA100 drive, in a single drive configuration.  The DiamondMax drive just edges out our perennial favorite WD drive here and shows an even larger margin of gain over the Barracuda.  In the RAID 0 test, the DiamondMax Plus 9 absolutely leaves the Barracuda V SATA RAID 0 array in the dust, showing more than a 40% lead on the competitive Seagate array.  The other notable is the DiamondMax Plus 9 is significantly less erratic, showing a much smoother bandwidth graph across the entire array, during RAID 0 testing. Finally, we're not all that confident in HD Tach's reporting of CPU utilization in these tests.  However, it does show the Maxtor DiamondMax Plus 9 is relatively efficient in that regard, even with a software RAID 0 setup, like the one we tested on the Silicon Image controller in our test system.

Winbench Business and Disk Access Winmarks

Next up is ZD's Winbench Disk Winmark suite.  Although this benchmark is a bit dated, with many legacy Business and Professional applications, used in testing, it still has is an excellent indicator, with respect to real-word desktop performance and overall throughput.  We used the most recent version 2.0 of the software, for our testing.


The Winbench Disk Access Winmark reports all drives here in this test, within one or two percent of each other, with respect to average access times, measured in milliseconds.  Since all drives tested here have a 7200 RPM spindle speed and similar specified access times, this is no real surprise.  Then the tables turn quickly for the Business Disk Winmark, in favor of the DiamondMax Plus 9 SATA drive.  It nearly matches the Seagate RAID 0 array performance, with only a single drive configuration!  Here the DiamondMax Plus 9 shows its real strength, with a 34% margin of performance over any single drive in this I/O intensive test.

The picture is becoming much clearer for the Maxtor DiamondMax Plus 9 SATA drive.  Let's turn up the workload a bit and then dig deeper into the stats.

High End Disk Winmark, Details And Final Analysis 

This is the test that separates the men from the boys, so to speak.  The High End Disk Winmark incorporates much more strenuous disk intensive tasks, like file transfers and data crunching in applications such as Adobe Premier, Photoshop, SoundForge and AVS Express.

High End Disk Winmark

We could just let this chart speak for itself really.  There is no explanation needed.  However, we can't resist commenting on what yet again looks like a proverbial "smoke-show".  For the single drive configurations, the DiamondMax Plus 9 SATA drive is 26% faster than the WD Special Edition drive and an unbelievable 82% faster than the Barracuda V SATA drive, nearly doubling it's performance.  In addition, if you are a Movie, Audio or Image Editing type, a RAID 0 array with a pair of DiamondMax Plus 9 SATA drives, seems pretty much like bandwidth nirvana.  You do the math.  Plain and simple, these new Maxtor drive are racing-stripe fast.

New Silicon Image Drivers and Disk Winbench Results

The rest of the individual test scores for each test in the Winbench suite, are detailed in the table below.  We've also taken the liberty of including a new set of numbers for the Maxtor DiamondMax Plus 9, in a single and RAID 0 configuration, with some new SATA Controller WinXP drivers, that were sent to us recently from Silicon Image.  These new scores are indicated with a bracketed "2" in the title column.  However, as you'll note, we used the previous revision drivers for the comparison charts in this review, since we didn't retest all the drives with the new drivers and wanted to keep a fair comparison.

Note:  "(2)" Test Run indicates new driver Set

The folks at Silicon Image have been doing their homework for sure.  As you'll note in this table of scores, the overall High End Disk Winmark performance of a RAID 0 SATA array, has gone up another 16% or so... sweetness.

A Note On Acoustics Of The DiamondMax Plus 9  SATA Drive:

Speaking of sweet, we're going to keep this segment both short and sweet.  We typically test a hard drive acoustic profile in a fairly primitive but effective none-the-less environment.  We literally place the drive down on a bare wood portion of our test bench and then let the drive's noise characteristics radiate through the wood.  This method actually enhances drive noise to a certain extent and gives a worst case scenario to gauge things with.  We didn't compare the drive to every disk in our lab but the DiamondMax Plus 9 SATA drive, has quieter spindle and read head acoustics, than either the Western Digital SE or Barracuda V drives we tested.


Final Analysis

It should be fairly obvious to you at this point, where this article and performance analysis of the new DiamondMax Plus 9 SATA drive, is culminating.  It doesn't take a rocket scientist to see that this drive is easily one of the best performing Desktop or Workstation Hard Drives on the market right now.  Historically, Western Digital Special Edition drives, with their 8MB buffer, have always been our drive of choice here, amongst the HH Tech Editor team.  However, with the advent of Serial ATA and it's inevitable succession of PATA technology, it's safe to say we have a new favorite.  The Maxtor DiamondMax Plus 9 SATA delivers on every performance metric, speed, speed, acoustics and... speed.

There are only a couple of small caveats with this new SATA drive from Maxtor.  Although clearly this is a high end product, the warranty from Maxtor for this type of drive is lack-luster.  Maxtor only warranties the drive for 1 year, while many other high end desktop products, like the WD SE drive, sport 3 year warranties.  We would like to urge Maxtor to reconsider upping the ante here.  Clearly this is a well built product, there is no reason not to stand behind it for a longer duration.  The other small issue is that you simply can't find this drive as of yet, in the retail channel.  Maxtor should be hitting volume with these drives in a month or so, we would expect.  As such, we don't have an MSRP for you on them either, as of yet.  However, one would expect that they should fall closely in line with the ATA133 version of the DiamondMax Plus 9 , somewhere around the $95 - 125 mark for an 80G unit, like the one we tested.

For now, we were so impressed the DiamondMax Plus 9 SATA drive, that we're giving it a 9 on the Heat Meter (3 years on the warranty would have scored it near a perfect 10) and our Editor's Choice Award for excellence.

(Model Number: 6Y200P0)

Manufacture Hype:

"The DiamondMax Plus 9 hard disk drive is designed to exceed previous standards for desktop performance. DimamondMax Plus 9 drivers are offered with industry-standard capacity points up to 200GB.

By delivering a performance hard drive using a highly leveraged design with state-of-the-art quality and reliability, Maxtor demonstrates technology leadership with DiamondMax Plus 9 Drives."


Size is an all important factor when it comes down to hard drives - 'bigger is better', especially with the advent of online media and users downloading files from the Internet.

The Maxtor DiamondMax Plus 9 model that I am looking at today, boasts a massive 200GB of storage space...

It also features a rotational speed of 7200 RPM, has an 8MB cache buffer and uses a ATA133 interface. The DiamondMax Plus 9 is also available with either a 2MB or 8MB buffer, ATA/133 or SATA interface and capacities of 60GB, 80GB, 120GB, 160GB and 200GB.

Along with the speed to back the hard drive up, this hard drive also is equipped with something called 'Fluid Dynamic Bearing (FDB)' Motors.

The Fluid Dynamics Bearing Motor is a fairly new technology that Maxtor has incorporated in their DiamondMax Plus 9 hard drives. This technology allows the drive to operate with a very low sound output - which makes the hard drive very much silent in operation, a great bonus for users who are concerned about sounds levels in their computer setup.


- Fast ATA/Enhanced IDE Compatible
- Ultra ATA/133 Data Transfer Speed
- Serial ATA version enables transfer speeds up to 150 MB/sec
- 2MB and 8MB Cache Buffer
- Quiet Drive Technology
- 100 % FDB (fluid dynamic bearing) motors
- Maxtor Shock Protection System
- Maxtor Data Protection System
- Average seek time: ≤9.4
- Rotational speed: 7200 RPM

In the Package:

The hard drive arrives in a fairly large retail box. Inside the box is a series of foam pads that protect the hard drive from shocks and damage before it gets to you. The hard drive itself is wrapped in an anti-static bag. Along with the hard drive, you also get a Multilingual Installation Guide (written in English, Danish, Dutch, French, Finnish, German, Italian, Portuguese and Spanish), an ATA interface cable, mounting screws, 5.25" mounting brackets and a MaxBlast Plus II Installation CD-ROM and Diskette.


Driver/Utility CD-ROM and Installation Guide

MaxBlast software will guide you through the entire installation process. Advanced users can simply skip this program and install and partition the hard drive as they please. The Installation Guide is very clear and takes you through numbered steps to install the hard drive (for example 'Configure the hard drive jumpers') and has labelled diagrams to aid you.

The inclusion of the 5.25" mounting brackets are quite useful and will be needed if you are to install the hard drive into a 5.25" device bay. Including mounting screws and a ATA interface cable also help to speed up the installation process, as you will not be hunting around for screws or a cable.

The Hard Drive:

The DiamondMax looks
similar to any other hard drive, with all the hidden features 'lurking' inside the sealed casing. The top of the casing has some useful information printed on it, such as the serial number, jumper configurations and manufacturing date. This particular hard drive used in the review, was manufactured on the 31st of January 2003.


The Hard Drive - 'Standard' Looks

At the rear of the hard drive, just like any other, is where all the connections are made. The only thing to note here is that there may be an extra spare (horizontal) jumper present. This does not affect the drives use and can be seen in the picture below.


Rear IDE, Jumper's & Power Connection


To test the performance of this hard drive, I will be using the popular benchmarking packages PCMark 2002, SiSoftware Sandra and HD Tach 2.61.

These programs will stress the hard drive and simulate reading and writing of data to it. The hard drive was connected to the motherboard using a rounded IDE cable on a primary connection. The results can be seen below in graph form.

- PCMark 2002: Results



- SiSoftware Sandra: Results


With an average access time of 6ms (milliseconds)

- HD Tach 2.61 (Demo): Results


With an average access time of 13.1ms (milliseconds)


This hard drive performed well in the tests that I conducted. It is jam packed with lots of storage space - together with speed, boasting a rotational speed of 7200 RPM and ATA133 IDE with a 8mb cache buffer.

SiSoftware Sandra reported the drives average access time to be 6ms and HD Tach 2.61 reported it to be 13.1 ms. Maxtor states that the drive has an average access time of less than or equal to 9.3ms. The HD Tach result does seem a little erroneous. However if we take the average of these two results, we get 9.6ms - which is more in line with what Maxtor says.

Reading and writing is reported almost the same in each test, the hard drive only seems to slow down when being randomly read or written to.

I found that the hard drive did run a little hot to touch after a few hours of usage, although this is common with most hard drives and especially the faster RPM models. Concerned users can always invest in extra cooling or a dedicated 'hard drive cooler' product. Although I had no data issues during testing and general use as of yet.

The hard drive arrives like a 'kit', with the inclusion of the 5.25" mounting brackets, mounting screws and a ATA interface cable. This is a great bonus, as you will not be hunting around for screws or a cable and can get straight in to installing the hard drive into your computer. The Installation Guide is very clear and easy to understand - less experienced users will find this Guide very useful.

Thanks to the 'Fluid Dynamic Bearing (FDB)' Motors, this hard drive also operates very silently. This hard drive is certainly one to consider if you are in the market for a new hard drive with a lot of storage space...
