Real World Tests - Multitasking Performance

To provide a real world example of multitasking, we run Outlook and import 450MB of emails into an account. We then time how long it takes our benchmarking utility to zip a single 300MB file. To compare our results, we calculate the difference between the multitasked process and the single task file zip process.

Outlook + Zip a 300MB File Within Drive
NCQ/TCQ Status Multitasked File Zip Only % Difference
Seagate 7200.9 500GB, 16MB, SATA w/out NCQ 69.215 59.707 15.9%
w/NCQ 69.512 59.785 16.27%
Hitachi T7K250 w/out NCQ 76.543 67.057 12.39%
w/NCQ 79.815 65.641 21.6%
Samsung HD160JJ w/out NCQ 71.484 58.805 21.6%
w/NCQ 73.554 61.068 20.4%
Western Digital WD1600JS N/A 74.371 61.182 21.6%

Seagate's 7200.9 did not disappoint here as its 3.0Gb/sec transfer rates helped speed things along. The difference between a stand-alone file zip operation versus a multitasked process was only about 16% compared to a +20% difference using the other drives.

    Once again NCQ did not aide these drives to deliver higher performance. It is my speculation that we will need an Operating System that can take advantage of NCQ before we could see any performance gains from it. Untill then Keep it disabled.

    NCQ is very vendor specific. Some drives benefit more than others from it.

    NCQ is actually beneficial in server applications where disk requests are occuring very frequently as opposed to a desktop PC scenario where disk access is not as critical.

    We are trying to research ways to benchmark this but if any of you have any suggestions, please feel free to send an email with any ideas you have.

    Thanks,

    with an icredible 5 year warranty i exclusively use seagate. Suprisingly i've never had a chance to test out Seagates replacement steps. I've returned dozens of WDs, Maxtors, and IBMs. Looks like seagates on a role.

    Such is life. I've seen quite a few Seagates die, yet, never had a problem with WD in more than 10 years of using them.

    One persons experience is hardly statistically correct. :)

    I own a 200gig Seagate 7200.7 SATA, and though the synthetic benchmarks like Winstone, Sysmark, Seagate is like at middle of pack most of the time, when it comes to like Real world tests like loading game levels Seagate is generally faster, sometimes even better than WD Raptor. The File zip times are pretty good as well.

    I'm always suprised at this, something that is average in synthetic benchmarks to do quite well in real world tests.

    I think its time to start shipping hardrive coolers standard with drive purchases like they do CPUs. hehe

    Well, I still wait the moment I'm supposed to say "Oh dear God this hard disk is fast!"...


    It qualifies in the middle of the disks, and under some conditions (in fact, only during the DOOM III loading test) stands out... but it falls short (VERY short) of impressing me...


    Did you ever noticed that, for example, during the zip test, the vast majority of the disks differ only by 4 or 5 seconds on a minute of encoding? And in the case of unzipping, it's down to 1 or 2 seconds? Where am I supposed to notice the greater speed?


    "I got the fastest hard drive in the world, I can zip my 300 MB files 3 seconds faster than you! You're jaleous, aren't you?"

    Yes, after the earlier promotional article about this drive, and now the title "Mouthwatering Benchmarks", I was expecting to be blown away by the blisteringly fast speed of the drive. It seemed pretty average really, nothing special at all apart from a high capacity (matched by a high price).
  • blackbrrd - Monday, October 24, 2005 - link

    I completely agree, having a title like "Seagate 7200.9 500GB: Mouthwatering Benchmarks" for this review is just wrong. Anandtech might get more hits in the short run, but looses credibility while doing so.

    I really don't like review sites that have misleading titles.
