Swap out hard-drive

I have a 1TB drive hooked up to my AppleTV and am actually running out of room and thinking of upgrading to a 2TB. Two questions:

  1. Any suggestions on a good, compatible 2TB+ drive
  2. When swapping drives is it as simple as just plugging them both into my laptop and copying all data from one to other then plugging the new one into my ATV?
