The difference is that IDE *HAS* to be able to saturate the bus (which it
can't, of course; show me an IDE drive that pushes even 66MB/sec off the
platter) for the bus speed to matter, since IDE doesn't support
disconnection. Multiple SCSI drives can be stuffing data over the SCSI
channel all at once. They don't have to be RAID'd, they can be different
filesystems accessed in parallel.
