Eric, thanks for your response. Shortly after my post I read several of yours and found the answer to my question.

>IDE drives are usually considered inferior to SCSI because it puts more load on the CPU <

Primary reason IDE drives are inferior: Both the IDE drive and the SCSI drive use up one IRQ (you only have 14 IRQs and some are used by the system). However, a SCSI card, using only one IRQ, can support up to 14 external items (drives, backups, scanners, etc.).
There are other reasons too. When rhapsody comes out one big problem would be having to write drivers for all the drives, backup tapes, etc. However if you use a SCSI card, the SCSI manufacturer has already done that. So all you have to do is write a driver for the SCSI card.
