The SATA cable is the weak link, one of many reasons Apple went to the PCI-e and soldered-in storage. They can be damaged quite easily if the unit is mishandled during assembly or re-assembly. This type of cable can experience cracks in traces due to aging, heat, vibration, impact and abrasion.

Those SATA cables are actually not cables but flexible circuit boards, usually mylar, with printed circuit traces taking the place of wires. As it cools down, electrical contact may once again be restored. This card should work with a SAMSUNG 860 EVO Series M.2 2280 1TB SATA SAMSUNG 860 EVO Series M.2. As a unit heats up, it expands, and as it expands, the crack widens, eventually forcing a complete electrical separation to exist on both sides of the crack, hence a failure. It's a Sintech M.2 (NGFF) SATA Card upgrade for 2012-Early 2013 MacBook PRO Retina SSD. In the case of an intermittent generic failure, the electrical continuity of a cracked trace on both sides of the crack is very often a function of the temperature of the unit at the point where the crack exists. Next, you'll need to unscrew the one Pentalobe. It is however no mystery why old cables fail when switching from HDD to SSD. The first step to changing over your SSD is to remove the 10 screws on the back cover of your MacBook Pro using a Pentalobe P5 screw driver. Agreed, a new SATA cable is a nominal expense and highly recommended.
