I'm switching my setup from an iMac that's always on with a 2TB external drive to a Macbook. I would like to move my iTunes Library consisting of Movies, TV Shows and Music, on to something hosted over the network that doesn't require iTunes to be running on a connected Mac. Which new external hard drive should I be looking to purchase? I've tried to do my own research but I'm confused by if there's a solution for this simple request. Talk of pin codes, fireflies... I already have an AirPort Extreme if that helps.
