any current issues with these bad boys? I need to jump up from the 320gb drive to a 500gb drive and would LOVE the speed increase.

I just did my latest TM backup so can I simply just remove my drive, replace it with the XT drive, insert my snow leopard disc, do a clean install and use migration assistant to get all my crap back on?

I'm worried about this drive though, noticeable battery drainage? are those sleep issues still happening?
