EDIT: I've decided on the new Seagate Momentus XT 500GB for a hard drive and Carbon Copy Cloner to help me set it up - now I just need a good, inexpensive enclusure to help set it up - preferably sold and shipped by amazon. Thanks to all who've helped! /EDIT I got my MacBook Pro a little under a year ago - a 2.26GHz 13.3" - which I absoultly adore. However, I hate one thing: its puny hard drive. I went for the baseline, since I wanted it ASAP at the time, but 160GB is really small, and it's almost full. I'm now finally going to upgrade it, now that I have only 30GB left (and a bunch of movies to add once upgraded), and I need some help and advice: 1) I don't have much cash, hence I was putting it off. If I can cut corners without cutting preformance and without possible future regret, I'd love to know. 2) What is the maximum height for a HDD in a MBP? Will a 12.5mm fit? 3) Whats the most cappacity I can fit in it? How much will it cost from a reputable retailer? 4) What's the best way to install a new HDD? I don't really want to buy an enclosure, but if I have it I want one with FW so I can at least reuse it with good speed. 5) How much louder and more power draining is a 7200RPM drive v.s. a 5400RPM drive? Thanks in advance! If you need any more clarification on this, I'll gladly give it to you. SG PS Sorry if there's something that answers these questions that I could have found by searching. A quick glance at the results I was getting didn't show me what I wanted, so I figured I'd have better luck outright asking.
