Hi10p will never be hardware accelerated. It missed the boat when it comes to industry support. It is too niche and will soon be replaced by H.265 (HEVC, High Efficiency Video Coding) which DOES have industry support.

If it's a modern drive then it can last for a few years worth of writing, and at that point you can buy a huge new SSD for cheap. Just backup anything of importance from the SSD to somewhere safe.
