Strange program. I run it on any of my 10K SCSI drives at it seems to work fine. 60K-ish with about 25% CPU utilization.
Run it on my 15K SCSI drive and utilization stays under 3%, only does a few tracks with a speed of under 1K, and my drive makes a strange high pitched sound I've never heard before. (not a seek sound)
The only difference in the setup of the drives is the 15K is set as a Dynamic Disk in XP.
All other benchmark programs behave normally.
