On Twitter and the Mac Rumors forum , which deals with Mac-related news, there is a report that 'an abnormally high frequency of drive writing is done on M1 equipped Mac in a short period of time', and SSD warranty in serious cases It is said that it consumes 10 to 13% of the total possible write data amount (TBW: TerraByte Written).

Users who actually use M1 equipped Macs have reported that 18.0TB of data was read and 15.7TB of data was written in two months. In other words, an average of about 12.5GB is read and about 10.9GB is written per hour, which clearly shows that the amount of reading and writing is abnormal.

Apple, this is NOT okay. Especially as the internal SSD isn't replaceable. The machine is just a bit over 2 months old. Pic.twitter.com/xqlSMjxwTa

Developer Hector Martin says that if the 256GB model continues to do the same, the SSD's lifespan could end in just six months.

2TB 16GB model. 3% used.

That means that for a 256GB model, proportionally, you'd expect ~ 30% usage.

If this is accurate, some of these machines aren't going to last half a year to 100%.

And that's a 16GB model. 8GB should be worse.

Holy shit. https://t.co/9HcmaYgJPT

At the time of writing the article, it is unknown why macOS reads and writes so much. Technology media ExtremeTech said, `` M1 Macs have a fundamentally different boot and recovery process than Intel Macs, so changes Apple has made to the storage system of M1 Macs are having an impact. Isn't it? '

In addition, since the increase in data read / write amount is too extreme and there is a report that 'an abnormality is seen in SSD read / write amount even on Intel-equipped MacBook', it is not due to the specifications of the M1 chip. , It has also been pointed out that it may be due to a software bug

what the hell, it's all swap. I have 32GB of RAM. Why is it doing this.
