My guess is that most of you have all four drive bays filled. For those planning on upgrading to the new MacPro, what are you doing with your current SATA drives? In my case drive 1 is programs and docs, drives 2 & 3 are media while drive 4 is used as a Time Machine. I'm thinking about getting a 2 or 3 drive enclosure and hanging my two media drives on the network via a port on my Time Capsule. My Time Machine drive I'll probably physically connect to one of the TB ports. Anyone know if they make any TB2 drive enclosures I can throw a SATA drive in?
