Real World Tests - Multitasking Performance

To provide a real world example of multitasking we use run Outlook and import 450MB of emails into an account. We then time how long it takes our benchmarking utlity 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.

Very disappointing. Hitachi's T7K250 performed better than the rest in this real world multitasking test...with NCQ turned off! Now, drive manufacturers list NCQ as a native feature, but it does not seem to work too well in real world situations. As we look at products in the future, we hope to see atleast some improvement given by Native Command Queuing.

    Our first benchmark shows Western Digital's WD1600JS coming in at second best in pure hard disk performance at 719 IO operations per second while the 74GB 15000RPM Raptor still tops the charts.

    Um... did I miss something? Aren't Raptors 10k in RPMs?

    When our publisher is away, with HTML we get to play!

    Sorry about that guys...everything should be good now. Do let us know if you see anything odd though.

    Thanks for stopping by!

    If I remember right, Wes said that their HTML coder was gone and they were doing all their own coding.
