What's the issue? Per iMore:
There are numerous reports from M1 Mac users that macOS is giving out worrying hard drive health reports which could indicate severe life span problems.
While it sounds pretty bad - especially considering Apple's exorbitant storage prices - it is unlikely to be anywhere near as bad as it sounds.
Some context is helpful.
Let's start with the fact that NAND flash - the underlying medium in almost all Solid State Drives - is a terrible storage medium. Which means there's a lot of firmware between your write and the medium that you hope it is stored on.
Some key issues include:
And there's more, like write amplification and read disturbs, that call for more controller acrobatics to mitigate.
Apple has some world-class SSD engineers. They've led the industry in integrating flash into their notebooks and in high bandwidth consumer SSDs in general.
I'm confident that whatever the problem users are seeing, Apple's engineers will be on top of it in short order.
But where is the problem likely to be? In order of likelihood:
Storage engineers are a different breed. They know that while everything else in a computer system can be reset by a power cycle, your data is the one part of the system that is not transient. Data corruption is a no-no, despite the fact that the universe hates your data.
Mistakes still happen though. I'd expect Apple storage engineers are working long hours to get a handle on this and a fix out the door.
As an owner of a newly minted M1 MacBook Air, am I worried? No.
Am I looking for a fix Real Soon Now? Yes.
