MacBook Hard Drive Upgrade - Which disks are compatible?

Almighty macrumors forum.

I am upgrading the internal hard drive in my MacBook, which shipped about two years ago with 75 !! gb disk. I want my next drive to have as much capacity as possible, but I heard from some retailer today that I can only upgrade to 160 gb. I can't see the rational - as long as it is a standard 2.5 inch sata drive, the capacity shouldn't really matter, right? Computer gets the data exactly the same way over sata, whatever disk capacity. So I was thinking ... is it a heat issue? RPM issue? How much can a slower rpm actually slows down the performance? So many questions ... so little time before i foolishly spend my paycheck.

Serial number for my macbook is W8716CZ5WGL

Any 2.5" 9mm SATA drive. Currently the biggest one is 500GB. I have a 7200RPM 320GB drive in mine. No heat, no noise.

Can you upgrade it if you have the AppleCare? Will it void this? What if something would break after I upgraded the hardrive, could I just swap out the bigger one for the original one to get it fixed? Would they be able to tell?

Yes, you can; and no they won't. If you want, you could swap back, but it shouldn't matter.
