So i finally did some PCmark2002, HDtach, sandra2002 testing, and I've encountered something strange.
I've got a 18GB 10K RPM U160 SCSI drive, and a 30GB 7200RPM ATA100 drive.
The ATA100 drive is besting the Ultra160 drive! Tell me there's something wrong with my U160 drive! Some benchmark numbers: PCmark2002 puts the SCSI drive at 555, and puts the ATA drive at 650.
Has anyone else experienced this?
