Please bare with me as I'm a casual Mac user and new to trying anything like what I'm about to describe. I want to set up a way to store pretty much everything in one location so that I can access it from either my iMac or MBP (I would also like to be able to do this from my iPad but this is not a deal breaker). I want to be able to get to it either on my wifi network or when away through the Internet. I would also like to be able to utilize the media from here on my Apple TV. The three ways I thought mi got work were 1. An airport time capsule 2. A western digital my book live 3. A NAS from Synology. Please tell me which is my best option and why the others won't work.
