But they tend to come in smaller capacity per drive. The choice to spend more for SCSI or SAS depends on the amount of disk IO you expect. Both SCSI and SAS are used for arrays more where you have a number of drives. Usually these drives are in hot-swap enclosures. -Derek -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
