I am trying to evaluate my NAS options.

1. 3 TB Time Capsule - single point of failure comment?

2. Airport Extreme - which hard disk? USB 2 performance issues?

3. NAS - which one? AFP issues with Lion.


Time Machine capability for iMac and Mackbook Air.
Be able to use Goodreader to access files (AFP server).
Be able to connect a USB FAT32 1TB drive to provide migration capability.

I am a complete Mac newbie. I have had the MBA for just a few months and the iMac is on BO. I would appreciate your help and expertise.
