I live in a 3 Mac household - two MacBooks and a mini as media center. Now I need more storage space to start digitalizing our huge DVD and CD collection and I'm thinking about buying a QNAP T-409 NAS. However, it's a lot money for a lot of stuff I don't need - actually, an external hard drive with 4 HD bays would be just fine, so I can connect that to our server-mini, format it in HFS+ with RAID 5 and completely manage it from there. Can someone here recommend something like that for me, or do you think I should invest in the NAS (despite not needing it's server functions and preferring HFS+)?! Thanks in advance!
