Exactly.  Enhanced IDE is just an attempt to CATCH UP TO the current
performance levels of SCSI.  At the same time, SCSI-3 is reaching for
grand new heights that even Enhanced IDE won't be able to dream.
IDE was designed, from the ground up, to be the cheapest solution full
of performance compromises.  If you run DOS, get IDE.  But if you want
real performance, bus-master SCSI is your best option.
