I can't really agree on that. The reason is that current SCSI drives
are either 10K or 15K rpm while SATA is 7200 or less for laptops. I
know I left out the Raptor as it is 10K but cost and is sized more as
a SCSI drive than a SATA.

The good reason is that SCSI drives have 1/2 the seek time of SATA
drives so performance with SCSI is greatly improved if you do a lot of
random reads/writes.
