My old Windows-based iTunes library is reaching its max capacity (My roommates and I rip everything we own to stream it up to the Apple TV on demand). The 500 GB setup I have is not enough, and it's on Windows XP - time to move to a Mac! I am trying to decide between two basic setups: A mac pro with 3 extra 1 TB Hard Drives, and a RAID card (for RAID 5), giving high performace and 2 TB of storage. A Mac mini with average specs, and a NAS to hold the data - most likely a Netgear ReadyNAS RND4000 with 4 1TB drives, for 3 TB of storage and some additional features (like built in DNLC and iTunes server capabilities). I've already weighed some pros and cons - the Mac Pro would definitely outperform the mini for ripping and other tasks (as a general household PC), but is more expensive. The mini + NAS has more storage and a lower cost, but lower performance and is more complex (2 boxes to manage instead of one unified system). Has anyone done the comparison already that can shed some light on this, and / or give advice on why NOT to take a certain path? Thank you for your help!
