Actual Application Performance

Our application benchmarks are designed to show application performance results with times being reported in seconds, lower scores thus being better. While these tests will show some differences between the drives it is important to understand we are no longer measuring the pure performance of the hard drive but how well our platform performs with each individual drive. The performance of a hard drive is an integral part of the computer platform but other factors such as memory, CPU, core logic, and even driver choice can play a major role in determining how well the hard drive performs in any given task.

Game Load Test

Our Sims 2: Open for Business test measures the time it takes to load the initial portion of the game. Our application timer starts when the game icon is initiated until the neighborhood menu appears.

Game Application Timing - Game Load Time

In this example of a real-world test, we can see that the differential between the fastest and slowest hard drives in our benchmarks has become considerably smaller. The Raptor and Hitachi continue to place first and second respectively, though the Western Digital WD7500AAKS now turns in numbers within a fraction of a second of those drives. Of note, the Seagate 7200.10 is still bested by the WD7500AAKS, but the real-world performance levels between the two drives (like those of the other drives) are significantly closer.

Game Level Load

This test centers on the actual loading of a playable level within our game selection. The Battlefield 2 test measures the time it takes to load the Daqing Oilfields level. Our application timer begins when the start single player icon is initiated and ends when the join game icon is visible.

Game Application Timing - Level Load Time

Continuing the real world example from above, the differential in level load times between the top performer (the Raptor) and the Western Digital WD7500AAKS is only one second (or 1.5 percent). From a price-performance standpoint, this speaks volumes, as the Raptor carries a price premium of $1.01 per GB of storage more than the WD7500AAKS. The Seagate 750GB drive is about 5% slower than our review drive in this test.

AnyDVD 6.1

Our next test has us utilizing the "ripping" function of AnyDVD to copy the Office Space DVD file from our source drive to our test drive. Our DVD features 29 files totaling 7.55GB of data and is an excellent test for determining the write speed of a drive.

Video Application Timing - Time to Transcode DVD

Western Digital drives extend their dominance in this benchmark, taking three out of the top four slots in our chart. The WD7500AAKS comes in slightly ahead of the Hitachi 1TB drive for the first time in the real-world benchmarks, and handily trounces the Seagate 750GB drive.

Nero Audio Encode

Our last test has us utilizing the audio encoding functions of Nero to convert our INXS Greatest Hits audio files in MP4 format to a high quality variable rate MP3 file for our portable player. Our test features 16 files totaling 137MB of data and is an excellent test for determining the read and write speed of a drive.

Audio Application Timing - MP4 to MP3 Conversion

The Hitachi 1TB manages to climb back above the Western Digital drive in this test, though the WD7500AAKS maintains its third-place position. The Seagate 750GB is once again handily defeated by the Western Digital drive, though the differential shrinks when the test shifts from a "mainly write" benchmark (as in the AnyDVD test) to a read-write combination test like this one.

    http://www.silentpcreview.com/forums/viewtopic.php...">Very good discussion concerning the problems with anandtech's sound measuring methodology here.
    quote:

    I really wasn't going to say anything here, but I feel compelled to do so. First, I almost completely disagree with nwavguy about the merits of close mic SPL measurement. The only good things about them are...

    1) you can use a poor SPL meter in an inadequate, noisy setting
    2) it's cheap

    The problems with Anandtech's methods are much greater than this, however. The HDDs are not even isloated from other noise sources which appear to be far louder than the HDDs being measured. That's totally illogical and careless if you're seeking any kind of accuracy in acoustical measurements.

    for Samsung to offer larger drives

    So...have all drives up to this point only had the drive shaft secured on one side? The end of the shaft just spinning in the air between the top platter and the casing? That seems like a very unlikely thing given how easily that could result in the platters moving and hitting the heads or even hitting the casing. Given the G forces they're rated to handle even when running makes it sound even less likely.

    Oh, and haven't all drives had auto-parking heads for like a decade or more? The only reason the heads would move onto the platter during spin-up is if the controller specifically drives the armature to do so. So basically, SecurePark is WD saying "hey, we don't do something stupid with the heads anymore!"

    I hate how every company has to give their own trademarked name to a basic technology that everybody has.

    I've noticed in stores 250, 320 and 400GB versions of AAKS are they the same revision drives? I'm ready to order one if so.
    Also, with the same capacities WD has drives in series KS.

    Please, I need support, I'm buying a new PC. Thank you

    Where did you find the Seagate for 180?
  • Gary Key - Thursday, August 9, 2007 - link

    At the time Dave wrote this, our price engine was showing ClubIT to have it for $188.89 if I remember right. I just checked and it was up to $199. We will get the article updated shortly.

    Fixed with a press of the refresh button... strange things today.
