Re: Hard Drives
Its important to know that SATA is soon to release SATA 6gbps (600 MB transfer rate), which would contend with SCSI highest's 640 (rarely on the market, Newegg only has up to 320s).
However, as freestyler pointed out SCSI is way too expensive for the benefits. The only reason to use one is as a "quickdrive," or a smaller 40-50 gb drive that is wicked fast used to put just your operating system on (speeds up overall system performance).
