Not a direct answer to your question, but be careful of SATA drives.

As I understand it SAS drives (Serially Attached SCSI) are designed
to handle server duty (multiple processes stepping the head 24/7),
whereas SATA drives (Serially attached ATA) are not.  SATA drives if
used in servers will fail prematurely.  They're great/cheap for home
use though.

I've also heard that SATA-2 drives are more like SAS or SCSI drives
in this respect, as in they're designed for server duty.

I probably heard the above on this very list in the past.

Can someone confirm or deny?  Making me look like a fool is ok, I'm
used to it.  ;-)
