Namely: a good quality housing for 2 hard drive 2 TB recognized by my TV. Indeed, given that the top players (including televisions) do not recognize the hard drives> 2TB, I carted my 2 hard disks acting as "video players" separately. The two appear in the Device TV! I imagine that for the raid, it must be good, but for a basic function with the 2 hd individually recognized is niquel too!
