Just basically wrong nowadays.

CPU load for IDE is same or less than SCSI,
I/O speeds can be the same with similar drives,
or faster with 10000rpm SCSI drives.

For a desktop machine with internal drives,
the rest is pretty much indistinguishable.

For high-end servers, or machines with external
drives, SCSI seems the way to go.
