I read a recent article on Tom's hardware that said, even given the same speed
of data from the read heads and the same buffer size, a SCSI drive will work
better for a server, and the IDE drive will work better for the desktop. The
caching algorithms are optimised with the assumption that a SCSI drive will BE
on a server and an IDE drive will BE on a desktop.
