Yes this is all bogus. As a single drive UDMA faster but two scsi drives
are still faster as with UDMA (Still IDE) you can only talk to one spindle
at a time. SCSI you can have seven on like and with some of the fancier
stuff you have the ability to talk to all of them! This makes a real
difference if you have system on one, Swap on another and Data on a third.
When you interleave like that with queued IO then the difference is
substantial. Also RAID with IDE is really flakey!
