I had a big problem with crucial 4tb ssds recently, using them as time machine drives. The first backup would succeed, the second would fail and the disk would then be unrepairable in disk utility, which also will refuse to format to non-apfs (and an apfs reformat wouldn't fix it). Switched to samsung t9s, so far so good.
