I'm looking to upgrade the HDD in my MBP...it looks like the biggest drives at 7200 RPM top out at 320GB? Newegg has two in stock, the Seagate Momentus 7200.3 and the WD Scorpio Black. Both are the same price, but it looks like the latency on the Seagate is a little lower. Any recommendations? Also, how do I go about migrating the contents of my current HDD to my new one? I have a Time Machine backup of my OS X partition on my external, but I need to transfer my Vista partition over too. Can I do this seamlessly (ie, without reinstalling anything)?
