hi everyone!
I have rb951G-2HnD with latest stable router OS version 3.36.2. I don’t write anything to the internal memory but value of sectors write since reboot increases. How can i stop it?

That’s okay. 6.36+ is more “hungry” to sector writes due to “refreshing” feature that keeps data integrity in place.
i don’t understand what does it mean “keeps data integrity in place.”? why it’s needed? This feature uses flash memory life for no reason. Linux can run without any records to disk using ram disk. May be mikrotik specifically limit the life cycle of their devices such firmware?
The problem is relevant. the problem is not solved.How to reduce writing to nand disk?
the new function for uniform wear of the disc is very harmful. how to turn it off?
use RouterOS v6.43.8 (stable)
One setting that results in very different number of writes to nand, is
/tool graphing
set store-every=
Shortest is 5 min, longest is 24 hours. Difference in number of writes is 288-times.
Another ex: dhcp server persist to disk.
Best to go over full config, step by step, and disable anything not absolutely needed.
