The SSD may be about worn out, or it could be a flaky sata cable.  I'm 
using rotating media, and I have so far collected 4 bad sata cables hanging 
on a cabinet knob, all made of the exact shade of the infamous copper 
eating red plastic I've had trouble with for 40+ years.  If your cables are 
red with a hint of magenta, give some other color of cable a try.  The red 
ones?  At 3 years old you can get any resistance you want on an ohmmeter, 
just flex them.
