I'm looking to setup an external hard drive with my airport extreme. Plan to use it for: Time machine backups Air drive I'm looking for about 500GB to 1TB. Ideally, the drive will be setup near my TV, so it is important that it is quiet. Any suggestions for an external drive? Order of importance: 1. Quiet 2. Size (500GB+) 3. Price 4. Looks I did search, but surprisingly did not find many relevant posts. If you are aware of any, please link to them. Thanks!
