Honestly, it's time to really rethink if the exercise is worth it. Often, it will cost you MORE (depending on where you live) to try and re-encode to save size.
With a 4TB hard drive, the cost per GB is ~$0.02 (Newegg shows many 4TB drives for ~$90). If you re-encode a movie and save 10GB that's a whole $0.20 savings.
There's more to that story however... Doing a processor intensive re-encode for 17 hours on a high end computer will burn ~450 Watts of power if you are maxing it out (add a monitor being on the whole time can push that to ~650 Watts... but let's say you turn that off).
450 Watts * 17 hours = 7.65 KW/hr.
Average energy cost in the US is $0.13 per KW/hr.
Cost to re-encode your movie: 7.65 * $0.13 = $0.99. Even if you have a super efficient computer and use only 100 Watts under load, that's still more over those 17 hours! (1.7 KW/hr * $0.13 per KW/hr = $0.22).
There are many factors that play in to the cost and your situation but essentially you are either even in cost or actually losing money by re-encoding. If dropping ~$90 in one chunk is more prohibitive than adding $5 - $10 / month to your power bill then re-encoding may be the way to go.
Considering you are on AVSForum, I'm guessing that looking at this from another perspective will push you towards more storage and keep the full visual and audio quality of your rips!
