I have been using 7200.11 drive for 10 months, there were firmware problems, but once I updated it, there weren't any problems at all. Check your drive for problems with seatools and if there's some issue, just RMA it/. seagate ass is quick, they will replace the drive in 3-5 days.
Most of the guys here seem to be happy with their wd 1tb green drive, opt for it if performance is not an issue.
