Currently I have 4x250g SATA drives in my main PC. As I travel a lot I want to be able to carry my storage with me. Unfortunately, carrying a 60lb case is out of the scope of what I want. What I am really looking for is a single box(save the power cord) that can do 4 SATA drives and can do USB or firewire connections. I've looked online via a google search and nothing really in my price range. I know it should be expensive, but I just wanted to make sure I'm not missing something cheaper, or something homebrew. Thanks!
