iirc, one reason is the ability of scsi to disconnect while doing it's job
freeing the cpu to wander about with it's tasks.

try doing a heavy dump of one or multiple IDE disks and watch your system
performance. repeat the task with scsi. scsi takes more housekeeping but
is smarter. of course the term smarter is my opinion :)
