Are those the same line of drives that had the "click of death"? I was wary of getting them, and got a Western Digital instead. Also I had a Deskstar 60GB that was dog slow before. I'd take a serious look at the Maxtor Diamondmax 10s instead. I've got one for my primary drive. They're as fast as the Raptors but at not such a price premium. They do have issues with my motherboard (A8N-SLI Deluxe), but I got that sorted out.
