I installed Mac OS on a 512gb T3 Samsung external SSD on my wife's 2013 iMac. It sped it up and was great for a while. A couple months ago it would crash randomly, but were now at a point where its crashing several times a day. We are in the process of backing up everything and about to try a fresh install to see if it stops. I fear the drive is dead and I'm sure were just out of the warranty period. Does anyone have any tips to fix this? Or experience with running Mac OS on an external SSD?
