I want to upgrade my playstation 3 fat of 80gb to at least an 250gb hard drive. I know the hard drive has to be 2.5 inches but I dont know which brand is best compatible with the ps3 and also if I should get a 5400RPM or a 7200RPM. I saw that the western digital wasnt good because it sometimes freezed in some games and was slow. So please I would aprreciate help from someon who knows about this topic. THANK YOU!
