Our long-delayed Maxtor DiamondMax Plus 9 review has finally arrived! Confusingly enough, Maxtor ships these drives featuring three different platter sizes. Though we can't tell you how to get the density of your choice, we can tell the difference, if any, in performance. Read on!

It is in the Bootup DriveMark, a rather unusual test that incorporates higher-than-normal queue depths where significant differences emerge. While the 80- and 60-gig units turn in similar scores, the 68 GB/platter DM+9 stumbles and falls significantly behind the other drives.

Any thoughts on why this occured?

Well I have to say this, the d740x is better than these drives by far, i wonder if i can still find them? The IBM does seem to be better for everything though, even over the 2000JB series. ANyway, i think that maxtor should be diligent to deliver the 250 MB plus 2 series, or else I am gonna sue them, real big.

The DM+9 significantly outperforms the D740X in all SR benchmarks. How can one reach the conclusion that the D740X is better? CompUSA and Best Buy are closing out the 120 GB model (labeled as 100 GB + 20 GB free).

Regarding a lawsuit against Maxtor, are you a SI that had a date-specific contract that they did not fulfill?

Curiosity: did SR do away with the "Safe Buy" standard? If not, I'm curious as to why this drive did not receive that distinction.

Eugene: what firmware versions are the different drives using?

I see that the seek time is quoted as <=9.4ms - it says that on the website now as well. Previously the website and datasheet said <9ms.

My 3-head 6Y080L0 measures 8.3ms, while my 2-head version measures 9.5ms.

Sounds like Maxtor is buying actuators from the "parts of the month club".

I'm very disappointed in the seek performance of my DM+9 60GB single-platter model, measured access time of 13.3-13.5ms using HDTach, my 30GB 75GXP two-platter model scores around 12.2-12.3ms.

I think these drives are akin to the Seagate Barracua IVs - quiet, FDB motors, but trailing the pack in terms of performance. Basically, designed to be quiet and cheap to make. Mine also gets quite warm during heavy activity - 57C as measured by MBM 5's SMART HD temp sensor, up from a 45C idle, during a formatting or surface-scan operation.

Is it just me or has Maxtor got about 200 different harddrive models out at the moment, with a whole range of crap and unintuitive names? Let's hope at least one of the 200 new models is more interesting than this one!

Well Virtual Larry, at least you are near specifications, cause I move from 2 60G to another 2 ones and only get 16msec; from there I changed the 2 60G and got a pair of 80G and voila!, now I have the astonishing value of 15msec.Great Maxtor!! Just within specifications!! Not to mention the recognizable sound of click click just when the drive is in the mood...

seeks are getting higher and higher with modern ide drives. It's gone downwards since the days of the Fireball LM+ (a whonderfull drive)

I'll stick with 10k scsi for windows and ata 7200 drives for data.

I remember reading when the new 80G per platter Maxtors were announced that the highest drive capacity will be something like 320GB. What happenned to these? Seems like I heard this 6 months ago here on Storage Review.

Does anyone know if the platter configuration identified on the drive?

Also, there is inconsistency on the Maxtor website as to whether or not the motors are in fact Fluid Dynamic Bearing (FDB). The general overview implies they do, but the spec sheet has an asterisked note that says only the 6YxxxLO 2mb models have it. An email response from Maxtor to my request for clarification said that "Maxtor is rapidly moving to all FDB drives".

:roll: you've read the spec. sheet :?:

What is it about

100% FDB (fluid dynamic bearing) motors

and

All DiamondMax Plus 9 drives are equipped with FDB motors.

that you don't understand ?

I am simply pointing out that the PDF data sheet (see chart top of page 2) indicates that only drives with an "L" in the model number have FDB motors, and Maxtor is not currently refuting that detail in my correspondance with them.

It's just bad editing - the previous version of the spec. sheet said

Note: L-FDB motor, P-8MB Buffer, M-SATA

..all are different from mine, which one do I own?

The lowest STR according to the review was above 53/33 MB/sec. My drive only runs at 50/25MB/sec. Doesn't fit into the SR measured categories in any way. Also, I only get 11 points in h2benchw, against 15 measured in this article http://www.hardware..../448/page8.html. Any ideas?

This is model 6Y120P0, 120GB, 8MB cache, bought last december.

Measured on both Epox 8KHA+ (VIA KT266A, Windows 2000/Linux, Athlon 1800+) and Epox 8RDA+ (Nvidia Nforce2, Windows XP, Athlon 2400+), no differences due to platform.

Maxtor DiamondMax Plus 9: They Are Different!
Posted 2/03/03 at 9:16 pm by Anton

Just days ago in our IDE Hard Disk Drives with 8MB Cache-Buffer roundup our own Nikita claimed that the DiamondMax Plus 9 lineup of HDDs from Maxtor is based on 60 and 70GB platters instead of 80GB platters depending on the model. It seems that he is [as always] fully right, but, apparently. there are, at least, some DM+9 hard disk drives based on the �fair� 80GB platters!

A reader pointed out that his new Maxtor 6Y080L0 is faster than the drives that were tested by our specialists for the review. He noted that the linear read speed in the beginning of his disk was 60MB/s, 10MB/s more than on all the 60GB platters-based HDDs tested by us and 4MB/s more compared to a Maxtor disk with 70GB platter. Summing up all the facts we easily come to a conclusion that a number of Maxtor HDDs implement 80GB platters!

How to distinguish between the �old� and the �new� 6Y080L0 HDDs? Well, there are two main differences between them:

The new disks are flashed with new firmware: YAR41BW0, while all the 60GB platters-based HDDs our Nikita has seen were flashed with YAR41VW0.
The HDDs with newer firmware seem to be manufactured not earlier than in mid-December.
Both points have not been confirmed and we cannot guarantee that the facts are right. At this point all we can is to allude and seek for the truth.
Honestly speaking we have no idea why Maxtor had decided to utilise slightly outdated 60GB platters, but there can be two reasons here. Firstly, Maxtor used to have technical problems with 80GB platters and rolled-back to good-old 60 and 70GB devices. Secondly, Maxtor simply had loads of old platters and utilised them in their new HDDs.

If you happen to buy a DiamondMax Plus 9 HDD one of these days, be sure to grab a newer version: they are considerably faster!


bud i rely more on sr :wink:
(i only registerd for this post :D but i read SR al the time)
keep up the good work.

Hmm,
I bought exactly same drive 6Y120P0 just two days ago :). Unfortunately, it is probably old version (firmware: YAR41VW0, mfg: 19.Nov.2002) and unfortunately it si louder than my old D740X 40GB (???), which I would not expect since the new drive should sport this fluid thing. I am probably giving up on that one to Seagate Barracuda V (ST3120024A). I need that drive for my home system, since now I used exclusively Maxtor (Diamond Max 60 Plus, D740X, even old Quantum was "maxtor like"), but now I feel like giving up some performance for the quietness. I would however not like to give up in terms of reliability.
Can anybode compare these two drivers?

..all are different from mine, which one do I own?

It is really a shame that my first post in this forum turned out to be quite a bullshit :| .
After I post the previous post, I decided to tackle the problem rather methodically, since I was not completely convinced that my new drive is really so bad.
I started to evalute the noise each drive produces by temporarily disabling other drives. I did it simply by detaching the power cable from each drive. I also can adjust fan speed manully for all fans in the system so I turned them off too (CPU fan just for short time).
After that experiment I must confirm that the new Maxtor 6Y120P0 is far more quiet that any other drive (Diamond Max 40 Plus - 30GB, D740X - 40GB).
The most noisy is D740X (it clearly whines with high pitch, compared to Diamond Max 9, which is almost not audible from 1 m). The bad luck is that during the tests my old Diamond Max 40 died on me :cry: . I do not know if it was because I disconnect the power and leave the IDE connected or because it was in rack, but it is no longer recognized by the Promise UATA 66. I tested Promise controller with another drive (actually the one I have had connected to it for almost 3 years and only recently moved it out) and it is OK.

You didn't unplug / plug with the power on, did you ? :(

This makes me thing what is power on and power off. I assume when I switch the power off by power button (soft-off) it is "power off", even the board is still powered (green LED lights), and I can for example remove the drive in the rack. To completely cut the power I would need to unplug the power cord (there is no switch on PS), which I am not sure is the way it was meant to be done.
Am I right?
Anyway, I always plug/unplug drives when system was "soft-off", in that state there should be no power on +5V and +12V rails.
What confuses me even more is, I have tried the deaf drive yesterday several times with no luck. Today I brought it to the company and put into my work machine and it worked right away.
Seems, that the instant I started posting on SR, my drives started challenging me :o .

Green LEDs ? Are you sure that the power button is set up to power-off or go to suspend. Normally when powered off there are no LEDs on, but when in suspend (S1) the power LED is still on. However, I used to have a motherboard (Soyo) that had an LED on it that showed it was connected to power ever when in the off state. The point of this was to warn users not to plug/unplug anything unless the system was unplugged at the wall socket. When an ATX system is "off" the PCI and AGP slots are still powered for example (so that cards can wake the system).

Orca: Yes, there is one green LED (ASUS TUSL2-C) that signals the board is simply still (partially) powered (even when the system is turned off). This for the case one want to remove or add additional PCI cards. I believe, it does not matter when removing HDD rack.
Either way, I have tested my Diamond Max 40 in my company machine (run powermax advanced test on it) and it reported itself error free. I must have some anomaly in my system :? and will investigate further.

I've been reading some threads on fatwallet, and some people have been claiming that their maxtor hard drives have been failing within about a year..I just got a Maxtor 120gb 8mb cache hard drive from Staples, and I'm debating whether or not to exchange it for a Western digital 120gb JB model...what do you guys think?
