Just need some advice from you guys. I just got a 2011 13" MBP with the stock 320gb drive. I am planning to upgrade the hard drive with either: Hitachi Travelstar 750gb Scorpio Black 750gb Scorpio Blue 1TB I would like to have the extra hard drive space, and was leaning towards the 1TB Blue. But I read that it did not fit in some of the older MBPs. Just wondering if anyone has a 13" MBP and has experience with any of these drives. Thanks in advance!
