I'm using and IDE drive and (three) SCSI drive's on my NetBSD system now, this
is with a 'multifunction-dont-get-much-cheaper-than-this' IDE controller 
(12 pounds) and a 'the-lowest-of-the-low' Seagate ST02 scsi controller, after
completly hacking (read: optimisation) the driver (thanks to Glen Overby) the
SCSI drives are *much* (very technical term) quicker than the IDE.
