If I get a T6 Roamio from Atlantic Broadband, can I upgrade the hard drive? They only have 1TB (it's basically a Roamio Plus). The monthly fee is barely more than a cable card so it would be a pretty good deal. I just need a bigger hard drive, and don't trust the expanders because they crash and you lose everything. I was just wondering if anyone has tried sticking in a bigger hard drive. Also, what features are not available on the T6 from ABB? I heard that it does not stream and that there is no Netflix app.
