I have four 2 tb drives that I want to use to store media and backup my computers. What do you suggests I use? I tried a synology NAS but had a hard time creating partitions and then moving my iTunes and iPhoto library to the NAS. Most of the media is my own but I would like to be able to access it from my iPad and from an Apple TV if I decide to purchase one later. I'd also like to share some media like certain movies and music to others.
