I'm guessing the archive vs replacement question is because with DTV you can add an ehd but it disables the internal drive. Is my assumption correct? If so, that is not how Dish does it, it is in addition to the internal drive and you can use multiple(2 at a single time, but unlimited amounts of drives) with the Dish system. Also, don't forget, if you go the Dish route, and you want to save an additional $50, message one of the pub members here and get a referral code from one of us. I would recommend one of these fine gentleman that want a Xbox One, and although I'm happy to give you one of my codes, I would receive limited benefits from it, since I already got one.
