Except there aren't reports of that. Just tried googling and couldn't find anything about SSD failure actually happening. What I did find was some fearmongering back in 2021 about whether it might become a thing, but it seems like it was entirely hypothetical and never actually happened.

Also the M1 has only been around for a little over 3 years. They can't be dying after 4 years because they're not that old.

Where are you getting all this misinformation from? And why are you motivated to be repeating it?
