Thanks for this information. That's actually really helpful for me to know in my server administration dealings. I _hate_ disk IO and disk thrash. I was aware of kernel stuff but completed eluded me that I could modify it. I put it to 7200
Good point, but I was more talking about distros designed for a smooth day-to-day experience. A user would probably want something like SquashFS (to save space on the SD card) and ZRAM (to conserve RAM) since all their files would be living there.
You can decrease the to-disk syncing to e.g. once per day.
```sysctl.conf vm.dirty_writeback_centisecs = 86400000 ```
