Solved!! - I had almost exactly the same symptoms with my 2012 MacBook Pro. SSD upgrade Super fast for a month, then suddenly became slower than ever. Symptoms included unable to keep up with keystrokes (really annoying), slow application loads, slow printing.

Solved!! - I had almost exactly the same symptoms with my 2011 MacBook Pro. SSD upgrade Super fast for a month, then suddenly became slower than ever. Symptoms included unable to keep up with keystrokes (really annoying), slow application loads, slow printing.
I tried just about everything suggested on the internet; Reset PRAM, SMC, the wear levelling (TRIM). Reinstalled a clean OS (Lion, Yosemite, and El Capitan). Nothing made the slightest difference. I bought a different drive (i had a samsung EVO) I read the OWC were great...no change.
Then one day the mac failed to find my hard drive. I was pretty ticked off by now. So my research for this problem went down a different road. And I ended up buying a replacement SATA cable [product|IF161-086] Fixed it completely - Mystery solved.
So if this post helps just one person avoid six months of torture I will be delighted.
