I just bought a retail Seagate 500gig Sata2 (300) drive at Frys for 119.00 out the door. Didn't really need it, but hey 500 Gig stores a lot of movies
(Personal Opinion) Most folks should be satisfied with the current level of Sata2 drives, unless you're doing something like video rendering and capture direct to drive. Then something in Raptor flavor would be the way to go if you didn't care to mess with SCSI. But I would still probably not use the Raptors as the main drive and leave that to a Sata 2 drive and only capture / render on the Raptors.
