I've got a 2012 Air with 128gb SSD only and I'm considering buying a Time Capsule to store my iPhoto and ITunes libraries and save some space. I'm planning to use 300gb for backup and the rest to store my stuff. The idea is to access all files from my Air and also my musics/videos from my Apple TV. Is the TC capable of doing that w/out losing performance/transfer speeds? if not, what do you recommend to me? Don't want to spend more than 400-500USD. Thanks guys!
