Real World Tests - Game Level Load Times

We have changed our Game Level Loading Time test to include two of the latest games, Doom 3 and Half-Life 2. Because of their high resolution textures and the large levels, the loading time for the levels of each game are long enough to help show a difference between each drive.

We have also included an older strategy game, Command & Conquer: Generals, because of its longer level load times. Though the game is a couple of years old, it still proves to be a good measure of performance data loading performance.

Doom 3 Level Loading Performance

Both Seagate drives loaded up Doom 3's cavernl level at around 32 seconds on average, which were the quickest level loads on the list. Even Western Digital's Raptor took a hearty 41.3 seconds to load the graphically intense level.

Half-Life 2 Level Loading Performance

We recieved the same results for Half-Life 2 and its d1_canals_01 level, which the 7200.8 loaded the fastest at 15.846 seconds with the 7200.7 following in close at 16.767 seconds. The Raptor followed closely behind the 7200.7 with a 17.133 average loading time.

Command & Conquer Generals Level Loading Performance

Though Command & Conquer: Generals did not give us as much of a spread as Doom 3 and Half-Life 2, it did show us where the 7200.8 and the others generally stood with strategy games. The majority of the drives took between 32 and 34 seconds to load up the first map in the GLA campaign. Maxtor's DiamondMax 10 came in at first place taking 32.233 seconds while the 7200.8 took an average of 33.9 to bring us the action.

    #29 - I found a similar test that includes a WD Caviar drive and from what I can tell it is not exactly lagging.

    In "WinBench99" page, you said "The Disk Transfer Rate test reads from the media in a linear fashion from the beginning (inner tracks) to the end (outer tracks)". It's false, the hard drives have the beginning tracks on the outside (well, exterior) of the platters, and the inner drives in the interior part. The reason is that while stationary, the read heads stay outside of the media, and they will reach the outer tracks sooner. Also, on the outer tracks the data density is increased, so the data read and write speed is increased also.

    I'd say you need to ditch Winbench 99 for transfer tests. It's physically impossible for drives to have the same transfer rate on the inside and outside of the platters. Not to mention that the ONLY drives that showed this behaviour were NCQ drives. I suspect what is happening is that the NCQ reordering is stuffing things up by reading the data out-of-order, and that the reordering process delivers the data in one (or several) burst blocks that do not correspond to the real transfer rate off the platters. Maybe HDTach might return more sensible numbers.

    Are you going to do some more HDD/NCQ testing when we get more dual core CPU's to test in multi-taking situations?
    The recent article on the Pentium D shows the benefits of NCQ combined with a dual core CPU (the single core CPU's didn't really show any improvement), so are you going to go more in depth hopefully soon (after you can publish results of AMD X2 CPU's)?

    How is the 7200.7 120Gb drive louder then a Raptor? My 7200.7 120Gb drive is near SILENT, no where loud as a Raptor. I think your measuring device is off forthe Acoustics test.

    #20 - Thats easy. Ignoring the Raptor they are lagging behind on the consumer front compared to others. Last I checked they still charge a fair amount extra for a drive with a FDB motor. The performance just hasnt been up to par either. The days when the "Special Edition" drives were great are gone.

    Purav, you did not explain why you chose to test with an nForce chipset over a chipset from intel.

    For one thing, nVidia's ATA controllers/drivers have a fairly poor track record. I still remember the multitude of problems that cropped up when people installed nVidia ATA drivers on their nForce2 motherboards. I run my nForce2-based computer with MS ATA drivers because I am too afraid that the nVidia drivers will wreck my system (that, and ExactAudioCopy does not recognize any optical drives with the nVidia drivers installed). Admittedly, these issues were driver-related, but then nVidia's checkered past does not boost my confidence in their ability to provide an nForce4 driver that actually works according to spec. Maybe we're seeing no boost with NCQ because of poor implementation, who knows. Testing with just one platform will not reveal such issues.

    Also, among other things intel is known for their rock-solid and impressively fast ATA controllers, so an intel chipset would be the obvious platform of choice for testing such new technologies as NCQ.

    "It's mentioned in the article that all of the 7200.8 drives use a 3x133gb platter configuration."

    This actually isn't true, from what I've read elsewhere. Read the following at StorageReview:
    http://www.storagereview.com/articles/200504/20050...

    It makes a lot more sense than the "leftover space" theorem.

    xsilver, the drive is not "guaranteed reliable." The only warranty is that if it breaks within five years, they will repair/replace it. There is a possibility that data can be lost from any portion of the drive. You have no way of knowing whether this additional space, if accessible, would be any less reliable than the rest of the drive. Yes, modifying the drive would probably void the warranty, but I'm wondering if Seagate is selling software-limited, yet physically identical drives at different prices, much like with ATI's 9500/9700.

    With NCQ on u get worst results than with it off.
    This may be good at servers, but no good at desktop.
    I’ll say its bad implemented but, all drivers seem to suffer.
    So no NCQ for me...
