I agree with Mlsstl's take, which is that RAID is not really important. What I need is to periodically backup the library to a separate drive and, ideally, store it offsite. I've just ordered a WB MyBook Studio II 2TB. If it works out, I'll need to get a second one, or something like it, to use for backup. The Studio II has Firewire as well as USB (and eSATA) connections. I'll try it in the music system connected via FW. If that doesn't work, I'll either place it on the other side of the wall and run FW through, or attach it to the router's USB port and access it wirelesly (I think that will work).
I have read that, if you are running USB from your computer to a DAC, you should not attach storage via USB also. Too much contention for the USB bus, or something like that.
