> NCQ SATA is almost a no-brainer. Feizhou, It is only a no brainer if you have no brains right? And I am quite certain that you do have some brains. 7200 rpm consumer sata drives are not designed for the same load and duty cycle as a 15k scsi unit... Plus, in general, you would need a special aftermarket controller and then again, what about hot swapping etc etc - rh -- Abba Communications Spokane, WA www.abbacomm.net
