In my opinion the reason for CMU findings is that even though SCSI
drives are made with better parts the SCSI drives spin the disks
faster (10K or 15K) and seek in half the time (causing higher stresses
on the mechanics) as a result about the same rate of failure as your
typical 7200 RPM SATA drive.
