- Other than the ability to hang 7 devices from one controller, the main
- advantage of SCSI is that the CPU can be off doing other things while
- the drive and controller carry out their commands. I don't believe
- this is true for IDE. Note that I'm talking about a real SCSI
- controller and not some little cheap thing that doesn't really meet
- the specs.
-
- If you are running something that is only single-tasking, like DOS,
- you'll probably be better off with IDE. They're cheaper and faster,
- although SCSI drives are typically available in larger sizes.

-
- SCSI is primarily ISA and EISA, although I've heard of at least one VL
- model.
