I will soon be adding a second Mac to my home network. Initially I planned on buying a external HD for the Mini but since I will be adding a iMac am now considering shared storage. What options and how well do these work with the Mac? What are you using? From what I've seen LaCie, Infrant, and Drobo are reasonable options and simple enough to implement. When connected to a router do these NAS/RAID devices show up as a mounted HD or in the Network section in finder? I would like redundancy, along with a central location to point iPhoto, iTunes, etc on each machine. Most of these devices allow for hot swaps I believe. Anyone have experience with these or others?
