Given that it's P2P, I'd expect there to be extra bandwidth and storage cost that is reserved for other users. If it is wholly P2P, then I would assume that possibly only 400GB (1/2 + redundancy for network failure) of that 1TB can be used for your data, if they have centralised backup servers then more. For the former this system would only be reliable if the data is used as a backup for files that don't change that often, and that other peers have a fast enough upload rate. This service does not seem any different from the other handful of P2P backup solutions [1] except for the included hardware. Maybe the difference is as a standalone network drive it would more difficult to restrict upload rate or switch off the program when you don't want to upload data. Also it is uncertain whether multiple drives are needed for the thing to work in separate locations, e.g. transferring files from office to home.
