M1 Mac owners are experiencing high SSD writes over short periods of time
For comparison here&#x27;s the nvme smart-log for my 2.5 year old X1 Carbon running Linux - used for VSCode&#x2F;compiles and browsing&#x2F;ssh etc.<p><pre><code>  carbonx  ~  sudo nvme smart-log &#x2F;dev&#x2F;nvme0n1

So around 8.2 TB written in 2.5 years of daily use. And I have had syncthing running on it past few months to sync some git repos as an experiment. (And I run a rolling release distro so lots of updates.) In comparison the M1 data posted here looks out of whack.<p>I generally use bpftrace to find if anything keeps writing to my SSD - for the most part I don&#x27;t find any misbehaving programs on modern Linux distros. Assuming dtrace still works on M1 Macs you might be able to find what is writing to the disk.
