I am looking at external primary storage for my new Mac Mini. The Mac's internal HDD will be replaced with a 60 GB SSD (plus 8 GB DRAM!), so all data needs to be stored externally.

I want:
- something redundant, so that a hard drive failure will merely require plugging in a replacement drive, rather than restoring from backup.
- smart enough that the hard drives need not be matched, one can be a 500 GB and the other a newer 1 TB, etc.
- fast enough that the Mac won't feel sluggish in iPhoto, iTunes, etc. The Mac gives me a choice of USB 2 or Ethernet.

What do you all like? If I choose an Ethernet (NAS) device, do I have to futz with Mac OS to get it reading my libraries right, or is it very simple?

This isn't going to be backup storage, that will remain single external drives via Time Capsule and other backup software.
