Greetings. I have a revision D "old" 17" MBP with a stock 160GB 540 rpm drive. The space is getting low and i want to change for a new, bigger and faster drive. I want a minimum 320GB (500GB would be great) one with 7200rpm, to speed things up (battery life and heat doesn't bother me). Since i'm not very into computer hardware recently, i want to know what are your suggestions for a new 7200rpm HD. I've read that the Seagate Momentum 500GB 7200rpm is a very good one, but what about, for instance, the WD Scorpio Black 320GB? I remember reading that some drives may not work very well with the MBP, that some may cause problems, die after a few days/weeks, so i want to hear your suggestions, real-life experiences of some who had change the internal HD to a 7200rpm and bigger one. Thanks in advance.
