Some M1 Mac users have started to highlight hard drive health reports that might possibly indicate severe life span problems for the device. iMore rounded up some of the issues.
The issue of ‘TBW’, or total bytes written, refers to the lifespan of an SSD… If the readings being given out from these machines is correct, developer Hector Martin says it could indicate that some machines “aren’t going to last half a year”… Martin does however state this is “definitely” a bug, however its unclear if that relates to the readings being given, or macOS behavior which is causing the readings to be abnormally high (but accurate). As PC Gamer notes in its report, smart monitoring tools “are notorious for misreporting” and this could be an M1 teething problem.
