That's not what I said. If you're going to quote me, get it right.

You say that SCSI disks are more expensive than comparable IDE disks. I
say that it's usually impossible to find an IDE disk that truly *is*
comparable to a SCSI disk - and when you do, you're generally comparing
the most recent IDE disk to an older SCSI disk.
If nothing but peak transfer rate is all that matters to you in a hard
drive, then yes, you can find comparable IDE and SCSI disks - but if
that's all that matters, you're being pretty short-sighted. And to
compare nothing but drive features when talking about your disk I/O
subsytem is also very short-sighted.
