I got a unibody mbp with the standard 5400rpm 250gb hdd. I just bought a 320gb 5400 rpm WD scorpio blue for my ps3, but now I'm thinking of putting it in my laptop. Is it worth the hassle? I have a 320gb external so I can backup all my osx stuff, but will I be able to back up my bootcamp partition? Will there be any real performance boost, or battery life decrease?
