Of course SCSI is better, but it costs more; a lot more, if you go for
Ultra-320 with hot swap (which is the standard, today). I know IDE is
slower, and I also know its performances collapse when many concurrent users
are accessing it... but, as usual, everything depends on the workload the
server is going to face.
Anyway, I think IDE RAID is definitely better than software RAID; and it
costs really *little* more than just buying two disks and mirroring them by
software, so it's worth it.
