We’re working hard on getting the TiVo Roamio upgraded beyond its current 3 TB limit. We’ve successfully been upgrading the Premiere line to 4 TB for a few years, so that’s been the largest DVR around.
Currently, we’ve got a 7 TB unit up and running. Not sure how soon we’ll have kits for it, but we’re pounding away at it to make sure it’s stable.
And, as soon as we’re certain it’s stable, you’ll be able to get 1120 hours of HD in your Roamio . . .
