  Myself, I'd still use SCSI.  IDE does well when you're only doing one
transaction at a time, but when you're trying to do two things at once,
responsiveness gets abominable.  SCSI does much better in that regard... and
since this is supposed to be a heavily-used db server, I imagine that there
will either be *nothing* hitting the disk (enough RAM), or *lots* of things
hitting it at once.  When our company first started out, we used to run our
server on an IDE drive, I still have nightmares about how badly it sucked.

   You're right, the GHz chips have dropped considerably since I last priced
them out.
