There was a lot of people like me who is the question of using a hard drive 7200 rev / min would risk of overheating and noise? Before I hesitate at length on the storage capacity and the revolutions / min I bent to it WD5000BPKT WD Black Mobile 2.5 "SATA II 7200 rev / min on my PS3 500GB Ultra Slim and I can tell you nikel it work and I noticed no overheating of the hard drive and almost as quiet as the original hard drive. By cons I would have liked to take a 750GB but it is said that the PS3 is not designed to handle more than 500gb so I did not want to take any risk on that side.
