Is aynone else using a 4 drive Drobo to serve as their iTunes library. I have 4 2TB drives in my drobo filled with about 1.5TB of content all from my iTunes library. What attracted me to the drobo was the redundent drive feature so if a drive goes down i do not lose my entire library. I know this isn't a traditional "back up" I have backed up about 700 gigs of my favorite content on an external drive as a secondary back up. Is there a better way to back up short of getting a 2nd drobo to strictly server as my current drobos back up? I have been considering getting 2 more 2X drives and putting them inside my Mac Pro making them 1 drive though a RAID and just using the drobo for content back up thorough Time Machine or CCC. Anybody have any other good ideas for handing such a large iTunes library?
