I'm toying with buying some storage for files, films etc at home. Maybe something like a NAS which I believe if I hook it up to my wireless router I can stream films / pictures to compatable TV's. For redundancy I'm told that its better to get two separate drives that fit into a housing so basically back everything up onto the two separate drives incase one fails. So I was thinking of getting something like x2 2 terabyte drives, 2 terabytes should give me plenty of storage for films, TV shows, pics etc shouldn't it.

So what brands / types do you recommend?
