Master/slave a couple of ide drives on a single interface. Mirror
them under NetWare. Watch the performance suck badly. Replace with
scsi. Be happy. (it's just an example that is very dramatic with

p.s. or you can put them on two separate interfaces (duplexing)
Be happy cheaper... replace netware with mars_nwe... be very happy.
