When examining bells and whistles, and since you are intending to move user files to the unit... Be sure to get one which offers data de-duplication. That can cut storage needs considerably! (NYC HQ has it; we lust for it!)
Be sure you understand how each "choice" handles snap-shotting. Above all, I'd say getting user files off the DCs is a must! -- Richard D.
