Only in raw sustained throughput maybe, but how much do you need that?
My old Quantum Atlas V 7200rpm scsi drives are slower in raw sustained throughput than most modern IDE drives, yet under normal use they perform faster than most. Why? For starters, access and seek times of these drives are extremely lower than IDE drives, and as most reads are little bits scattered all over the drive, SCSI drives are done reading while IDE is still seeking (ok, lil over eggerated(sp))
IDE raid setups only make this worse, as although sustained throughput gets almost doubled, access/seek times usually double too to that of the single drive.
