What hard drive is used for the 500 GB Macbook Pro option from Apple?
I have been using a Western Digital Scorpio Blue 500GB in my June 2009 MBP without any problems. I have tried the Seagate 7200 rpm 2.5" 500 GB as well, but that did warm up and vibrate more than I liked, so moved it to my Mac Mini at home, where it behaves OK.
