Future MacBook Pro user has question

The restore was successfull finally the only thing I couldn't restore the el capitan or yosemite just the mountain lion (probably because I have only 8GB of RAM).

- 8 GB wouldn't prevent you from running the latest OS. Even the latest Retina MacBook Pros come with 8GB standard.

Look forward to hearing how you get on with your machine.

This is true. Most, if not all, 2011 MBPs cannot use SSD in optical bay. I tried it on mine and no go.
Some people have claimed they have been successful in putting a SSD in the optical drive bay of 2011 MBP though. But I think most will NOT work.

2011 Optical bay will support 3G SSD's not 6Gs. Tried a 6G 1T in optibay and it failed, 3G 1T worked.
