My laptop hard drive is filling up quickly, which made me think I probably want to upgrade in the near future to a larger size (my current one is 320GB). You see, I'm a fairly heave iTunes user, with some HD tv shows and movies, and I also like to import my CDs using apple lossless, which results in pretty large file sizes. My question is, how much performance gain would i notice by going from 5400 RPM to 7200? Also, does any hard drive work with any laptop? The one I'm looking at is http://accessories.us.dell.com/sna/productdetail.aspx?sku=A2340540&cs=04&c=us&l=en&dgc=SS&cid=52102&lid=1342490. Would this work with my HP G60 laptop? I suppose I should also mention that I do some light gaming on my laptop, such as The Orange Box.
