   I heard that a disadvantage of IDE was that master and slave received the
same address commands. This could cause multiple discs to search for every
address, causing excessive mechanical wear. Other suggestions were that SCSI
discs have better bearings, are assembled with greater care, and subjected
to more extensive testing. They may use semicondutors and other components
designed and manufactured to a higher "military" spec, for use under extreme
conditions. Some drives are guaranteed for very long life, but is a better
guarantee paid for by the increased price? I suspect that we may treat
explanations in the same manner as we treat government spin.
