When something runs well, do you really need it to run faster ? :)

Do you really time these? *grin*

Low end SCSI kit can often be outperformed by modern IDE kit. SCSI and
other business-oriented disk subsystems are desgined for heavy use at
high throughput. A lot about IDE is about peak performance, but don't
ask it to sustain it.
