I probably should have elaborated on this. If you are looking at SCSI
for performance reasons then cost has to be a secondary consideration.
If you think a cheap SCSI solution is going to perform as well as a
good RLL solution, then you have made a mistake.
I agree, wholeheartily with your response. There are other reasons to
look at SCSI than just performance, but I have gotten so much hate mail
about this topic that I have now started to take a hard line, when it
comes to the users idealistic meaning of what SCSI will bring him/her.
