What hard drive is used for the 500 GB Macbook Pro option from Apple? I'm looking to replace my Macbook Pro 13" hard drive. I tried upgrading to a Seagate Momentus XT 500 GB, but returned the drive because it caused the palm rest to vibrate when pressed (I installed correctly; the problem disappeared when I swapped back the stock drive). 

What drive is used by Apple as the 500 GB option (for both the 7200 and 5400 RPM) when ordering from their store (I figure this should be a good option)? Anyone else have experience with any large notebook drives that don't cause vibration or noise issues? Performance is a second to not having a computer that irritates my senses to no end.
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.
