Hardrive Speed

Recommended Posts

Is this slow or standard? I dont think it is very fast but it really slows my xbench down.


My total xbench score is around 160 usually. Without hardrive its like 270. The hardrive test alone is about 50

THe results are normal.

But: 1.) It depends on the Harddrive you use. In my experience, WD AAKS drives are fast. Setting up a Raid 0 (Software) with 2 AAKS results in a disk score of 142 here.

2.) XBench is not really a good bench tool. So dont believe too much what it tells.

Yes, it's not unusual to get some less than attractive numbers especially on the random benchmarks. As rhalls said, don't put too much stock in them. From personal experience, I don't think the drive speed numbers in and of themselves represent a lot in the real world. I've got a Maxtor Diamond drive that gets a total Disk Test score of 119. Then I've got a WD Raptor 10K RPM drive that only scores in the 60's. In real life, the WD drive is noticeably faster.
