Just recently got the "front-end" of my home theater setup sorted out and looking to do the same for the "back-end". Currently my iTunes library is on a 2TB USB 3.0 external hard drive directly connected to my MBP, i manually back it up to a 1TB wireless hard drive using CCC and it streams to a 3rd generation Apple TV. I need to decide on two things, how to manage the library and how to store it. My budget for all of this is 500$-1000$ The big question is whether or not to get a Mac mini. I love the idea of getting one just not sure if the cost is worth the use i will put it to. It would be nice to have a backup computer, would let me move my laptop around more and even leave it in the office sometimes and i could use it to run plex or other content management software. As far as storage goes i have a few options, considering a couple of mini stacks, a Drobo 5D or maybe a Western Digital My Thunderbolt Duo, trying to stay away from wireless storage because it is so brutally slow to transfer in or out large amounts of data, still don't understand why they don't make NAS's that have USB 3.0 connections when you need the extra speed but oh well. That is about it, i need a comprehensive solution to manage and store my iTunes library that currently has about 400GB and is growing at about 100GB month not to mention the very large DVD and blu ray collection i still have to rip for it. Any thoughts or suggestions?
