More news, and a possible solution...

Apple Hardware Test showed some SATA error, which I supposed could be cable related. Teetotal reported no errors. I got a new SSD, Samsung 850EVO, instead of Crucial mx100 that caused problems. Replaced, and ... no problems found in AHT.

I did not enable TRIM in OS X 10.10, wondering if this could have caused the issue, I don't think so, because the performance with Crucial was so poor even before I enabled TRIM. Please advice, if you have any suggestions, I know the Samsung have some garbage collection on their own...

anyway: looks like the performance problem and AHT SATA problem could have been caused by the Crucial SSD, with Samsung it looks fine, so far, and the performance is great, no AHT errors (TRIM not enabled).
