The only thing against SCSI is cost in my opinion. I have always run SCSI hard drives, so I obviously chose a SCSI Plextor (I didn't need to go out and buy a new controller).

If you already have a good SCSI controller, then you might as well get the SCSI UltraPlex40max. If you don't, I'm sure you're pretty safe with one of their IDE models (perhaps even a writer if that would interest you). Put it on a different channel than your IDE hard drive.
