It's funny how people with SCSI systems often seek to put down EIDE, and at the
same time make ridiculous performance claims for SCSI. Maybe its because they
have paid twice as much for their disk storage, and feel a need to justify its
cost, even if by inventing performance figures?

If the Seagate Cheetah can do 14-21 MB/sec, I doubt you are seeing continuous
40MB/sec. The fact is in a typical workstation, SCSI offers little or no benefit
to the overall performance of the system. If you don't believe me, see
