Hyperdeck 2 recording time?

How much recording time can one get using the compressed HD option per GB?. Looking to record 2 hour live programs.

If you are talking about the Hyperdeck Shuttle 2, its compressed codec is DNxHD 220x. This records 1080 at 220Mb/second (or 27.5 MB/second). So you can calculate that against how many Gigs are on the drive (varies by size of drive of course).
