Apple has fixed the SSD wear reporting problem in macOS 11.4
At the beginning of this year, some Apple users complained that the use of the M1 Mac will have SSD wear reporting problems, resulting in serious wear, which will reduce the service life of the SSD. Since a Mac equipped with M1 can only have 16GB of memory at most, if the memory is not enough, it will use SSD as virtual memory.
One of the indicators of SSD is the Terabytes Written (TBW). At that time, many Apple users reported that the SSD write capacity of their Mac was abnormally high within a few months after the purchase. According to the investigation and analysis of relevant computer technicians, it is shown that the consumption of the writing volume is proportional to the capacity of the SSD, which means that the smaller the capacity of the SSD, the faster the writing volume will be consumed. Of course, some people questioned the accuracy of the data, believing that the actual situation has been exaggerated, or that it was just a software reading error.
Apple has not commented on this matter, neither confirmed the existence of the problem nor denied it. According to Appleinsider reports, some sources pointed out, Apple’s SSD itself and its firmware should be no problem, the tool software that has detected this problem has a “data reporting error” situation that can not fully reflect the real situation, and not every Mac user who uses M1 will encounter such problems.
Update on the macOS SSD thrashing issue: It seems the issue is fixed in 11.4. Feel free to try the betas if you're adventurous, or wait for the final release.
It's going to be interesting diffing the XNU kernel source once it drops and seeing what the bug was…
