If you have a new M1 Mac, you probably think it will take years and years, but some new worrying data suggests that this may not be the case. More than a few users report that SSDs on Apple’s M1 Macs may be overused by the system, which could cause them to wear out sooner than usual.
Twitter user @never_released started a thread that shows a report of an M1 Mac with very high write scores for a computer that is only two months old. This led to other M1 owners leading the same report, and many also found excessive use, including Macworld columnist Dan Moren.

Twitter SSDs are preferred over traditional hard drives because they are much faster, but SSDs have a limited lifespan. An SSD expires every time you write to it, and eventually the disk will have problems and will probably need to be replaced. However, it is supposed to take a few years before MacOS distributes the script over an SSD to extend its life. Based on these readings, this can happen much sooner than expected.
There may be a bug in the reporting tool, but it is also possible that macOS is doing something to the SSD to cause these spikes. If this is the case, it’s a concern because the SSD drive on this new Mac cannot be used by the user and it costs hundreds of dollars to replace it.
We’ve been targeting Apple for comment and will update this story when we hear it.
