I don't have to depend on these files on the Samsung to be my only copy.  I just hope the SATA cable is good because it's inside a NUC and it's custom to that NUC.

Jim the wear life of a 1T SSD is probably greater than yours, so is the SSD failing or maybe motherboard (you use nucs don’t you)
The Samsung is not a SATA device (nvme), so are any other devices SATA ?
As Jay suggested spelunk with smartmon.
You have got a daily (1T might even be weekly) trim setup?
