Is it alright to upgrade the hdd speed in a notebook that's 2 years old? I need a new hdd, but I want it faster. Would this be likely to cause problems? Its original speed was 4200 rpm, I want more.

I leave it plugged in for the most part, so I don't think power should be that much of an issue... but would it?

it would drain the batt faster yes. I doubt the speed would make a noticable difference though. The only time ive ever noted a disk being particualrly faster than another one is with those server drives that are like 15000 rpm

alright, well I might get a faster one, but I might not. I actually spent most of my money for a new hdd on a 6 ft sword. ^_^ I have a friend, though, but he might not sell his to me cheap.

Thanks for the info, I'll keep it in mind. ^_^
