Scott - apparently we have a bunch of amateurs here
This box has 4.7 tb at the moment. But that can change at any time as I have a Blac X Duet that I can hot swap any of the 3.5 tb worth of drives sitting here on my desk.
The box right next to this one (used as a server) has 3.5 tb currently that I will be adding another 1.5 or 2 tb drive to shortly (have 4 320gig drives that are full of MP3's that need to be combined on one drive).
