We provide data services to our clients. We are already seeing USB enclosures routinely provided to us by our clients with 1TB. 1.5TB on occasion. 2TB usb enclosures can't be far behind. For usb a bigger factor than anything is when will MS offer compatibility/supportfor 2TB+ drives. As soon as they become readily supported in MS, our clients will start buying them and filling them up and we will need to be able to access them from all of our systems. (old and new).
