Maxtor's MaXLine III 250GB: Bringing 16MB Buffers and NCQ to Hard Drives

Game Loading Performance
For our game loading tests, we used two games: Far Cry and Unreal Tournament 2004. Both games were installed, in full, to the hard drive. We then used no-CD patches to prevent any accessing of the CD/DVD drive to skew the loading process. Both games were installed to a clean drive without anything else present on the drive (the OS is located on a separate drive).Our Far Cry test consists of starting a campaign with the default difficulty level, hitting Escape to skip the introductory movie, and beginning the stop watch timer at first sight of the loading screen. The stop watch timer is stopped as soon as the loading screen disappears. The test is repeated three times with the final score reported being an average of the three. In order to avoid the effects of caching, we reboot between runs. All times are reported in seconds, lower scores obviously being better.
The larger buffer doesn't seem to help Maxtor here as the MaXLine posts competitive, but not amazing, performance scores.
Our Unreal Tournament 2004 test uses the full version of the game and leaves all settings on defaults. After launching the game, we select Instant Action from the menu, choose Assault mode and select the Robot Factory level. The stop watch timer is started right after the Play button is clicked, and stopped when the loading screen disappears. The test is repeated three times with the final score reported being an average of the three. In order to avoid the effects of caching, we reboot between runs. All times are reported in seconds, lower scores obviously being better.
In UT, the performance of the MaXLine III is a bit more impressive, but still unable to dethrone the Raptor. We've found that our UT test is much heavier on the sequential transfers and thus, the 16MB buffer manages to help out a bit here. Once again, no benefit to NCQ in applications that are already very sequential in nature.

While the the article stresses that the tests attempt to duplicate real world conditions I noticed that, at least for the one benchmark, the o/s is on a separate drive. IMO most "real world" systems contain one drive, or at least one logical drive (RAID). Having the o/s and swap file on the same drive would, I suspect (and even with 1GB of RAM which is a little over the top), tend to highlight the difference between NCQ and TCQ performance.NCQ should only make a real difference when disk head movement is the bottleneck. A test such as loading a big program isn't going to really test anything unless the program is fragmented or some o/s activity (like swapping) concurrently takes place on the drive.
I also wonder how much of the advantages of NCQ are negated by the bigger cache? 16MB in a desktop environment is significant. It may well account for the closeness of the numbers reported.

Thanks for the responses guys, we're committed to making our storage coverage top notch on par with the articles in our other sections so it's going to take lots of constructive criticism to make sure we're providing that; keep it coming.You've already noticed that there were no sound/heat tests in the article. We got great response from the MP3s I posted of the drives in our first HDD roundup under the new suite, but we're still lacking a good quantitative way of comparing the sound levels of these hard drives. In the worst case scenario I could always just use a trusty SPL meter, but I want to do something a little more useful. Give me another week or so and I'll see if I can't at least have a prototype of what I'm trying to do.
In terms of our excitement about NCQ, the conclusion never stated that NCQ increased performance tremendously across the board. But also remember that we only had three heavy-multitasking benchmarks, and the performance boost we saw in one of them (a very common scenario, who doesn't copy a file and browse the net or check email?) was nothing short of outstanding. NCQ is sort of like Hyper Threading in the sense that it doesn't improve performance by 20% across the board, but in a few very real world scenarios, the performance boost is nothing short of impressive. And as workloads become more parallelized in nature, we'll continue to see bigger benefits from NCQ. For current sequential desktop applications, NCQ doesn't do anything at all; but remember that AMD and Intel are both going down the multicore CPU route for a reason - desktop usage patterns are changing. We're very excited about NCQ as a technology because it anticipates that changing environment and definitely improves performance in it.
Will you see a performance boost from NCQ today? If you're a heavy multitasker at all, then yes. Otherwise, no. Just ask yourself, how many times have you copied a file while doing other things in the background. A 10% performance gain in that one test is much more than any other real world hard drive performance improvement we've seen in recent history.
Take care,
Anand

I thought it was a pretty good article. I don't know where your people are coming from saying sounds like Maxtor PR paper. It may not be as fast as the raptor but then again it's a 250-300 gig drive not 74, fair trade if you ask me.As far as noise goes it should be identical to Diamond Max series. There is no reason for it to be any louder, aside from the 16 meg buffer and NCQ the drive is most likely identical mechanically.

So, I am also curious, how loud is it? How much will it cost?MaxLine or Raptor?
Seems to me, as a gamer, Raptor won in all the gaming related benchmarks.

I agree with #11. I got the same impression aftering reading the conclusion which didn't seem to take any of the rest of the article into account. The conclusion seemed to be based in wishful thinking of what he had wanted to see, rather than being based on the numbers his article actually produced, which were not nearly as positive.The Raptor does not support NCQ. It supports the old ATA TCQ which is inferior in its implementation. However, looking at the lackluster performance of NCQ, it's not hard to believe the even worse #'s that StorageReview just posted on the Raptor's TCQ performance in workstation benchmarks.
Also, the 7200.7's do not support NCQ either. Seagate announced a new version of the 7200.7 that will, but has not reached the market yet.

What would make it any louder than Maxtor's other 7200 RPM drives? I doubt they'd go back to using ball bearings and noisy servo's just to give us NCQ.T8000 - Friday, June 25, 2004 - link
It would indeed be interesting to see how other drives that support NCQ, like the Seagate and the Raptor 74 GB would benefit from it.Altough, I am not sure if the Raptor has NCQ or TCQ, but that could make it even more interesting, as NCQ and TCQ could be compared.

This article reads like Maxtor promotional copy, giving the Maxtor high praise in tests where it fails to even outpace it's 7200RPM competition. Also, like #9 said, how loud is it? Vibration? Heat? Interesting omissions to the article... bet it sounds like a jet turbine given my past experiences with Maxtor.bwall04 - Friday, June 25, 2004 - link
I'm not sure why this was overlooked but the 74GB Raptor supports NCQ. I think it would paint a clearer picture of the performance of NCQ and situations where it is beneficial if the review could be edited to add in these results.Kudos to Maxtor for stepping up with something to compete with my Raptors, and with 3x the storage!!

How loud is it?
