I've got the 500Mb OEM version of same drive. Had it running for about 3 months now - no problems, runs quiet (or at least quieter than the case fan), and seems pretty quick.
SATA2 - check 7200 rpm - check price - check quick google to make sure it's not a buggy pos - check
It's a brand new model so reports are still trickling in on it. WD is my preferred HD brand of choice at the moment. They finally got around to making their drives quiet to go along with their top notch performance. Seagate drives, in comparison, seem to get slower with each revision.
Bought and Bought. My wife's PC had to go into the shop to get a new case, so I'm getting them to throw one of those in as well. Picked one up for my own box as well while I was at it.
