I wouldn't mind doing it manually once in a while since it is a pretty straight forward process, just time consuming to do. Big file + MD5 check. Move big file to SSD + do another MD5 check. Should match if all is well.

I have some more advanced methods I can use too with some of the tools I have here. Write LBA number pattern into every LBA and then read it back to see if everything is perfectly correct. I'll probably just do MD5 though.
Writing each LBA sector would be better than a plain MD5. It would show us at the end how many errors were encountered at bit level.
