Pros: Quiet, Fast, Cooooool
Cons: 5400rpm, if that's really a con for a storage drive?
Bought 10 of these babies for my file server earlier in the year. I've never been so impressed. They were taking the place of WD Black 1TB's and boy was I surprised when I popped them in. They are quieter, much cooler, and even faster than the WD 1TB counterparts. WD still has the best RMA service I've encountered, but considering they bought Hitachi, I will be a very happy camper for RMA's in the future.
