SCSI evolved into a whole family of standards a long time ago. SPI (SCSI Parallel Interface) has been obsolete for a while now, really. SAS does have some things over SATA (longer distances, more consistent implementation of hotswap, maybe some other stuff I forgot), but for the most part SATA is good enough for almost everything. But even then, SATA borrows several things from other SCSI standards. SATA and SAS are so similar it's hard to tell them apart at times. One could argue that SATA is as much SCSI as it is "AT Attachment". Your optical SATA drive almost certainly uses the SCSI MMC command set, for example. And then there's iSCSI. Cheap SATA disks on a standard mobo, exported via iSCSI. In other words: SCSI is dead, long live SCSI. :-) -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin
