PCMark05

And now I will try to evaluate the performance of the drives using Futuremark’s PCMark05. Besides everything else, this benchmark includes a set of hard disk drive tests. The tests are simple: the user can run the drive along a prefabricated trace. A trace is in fact a log of access to some “default” hard disk drive which was mercilessly tested in Futuremark’s laboratories.

The benchmark offers five traces in total:

  • XP Startup
  • Application Loading
  • General Usage
  • Virus Scan
  • File Write

The tests can be run separately or all in a batch. I chose the second option, perhaps wrongly.

The fact is each decent hard disk drive wants to be a “black box”. And it wants to be a block box that reacts to a request on its input depending on the entire history of earlier requests. By running the tests in a batch, we pass the drive through all the traces one by one. It doesn’t have time enough to get used to one trace, but we already start another.

On the other hand, it would be strange to run the XP Startup trace a dozen of times because it is assumed that the booting of the OS is done after a cold or warm restart of the computer, and at this moment the hard drive is reinitialized, i.e. the accumulated access statistics is cleared and the drive is reset into some “initial” state.

Anyway, the test conditions were the same for all the participating devices, so we can compare the results.

So, the WD1500AHFD is again on top. The “wild” WD740GD can provide some competition to it on the XP Startup trace, but on all the other traces the Raptor X is unrivalled.

I’m rather doubtful about the results of the drives on the Virus Scan and File Write traces because the measured speed of the drives is higher than they can physically do.
