Questions raised about M1 Mac SSD longevity, based on incomplete data

Complaints about the potential lifespan of Apple Silicon Mac storage are causing concern that the current crop of M1 Macs could stop working within a few years — and have been stoked by unanswered questions, unreliable data, and a silent Apple.

Since the middle of February, social media postings by some M1 Mac users looking into the health of their computer’s storage have raised potential issues that they see with their new devices.
