Here’s the report:

I’ve disabled dhcp write to disk, graphing store every 24 hours, web proxy disabled, dns server 10240kb. Why write sector written still so high? It count up about 30 sectors every 2-3 seconds. Anything wrong?

edit: Written sectors reached 1 million in 23 hours 54 minutes. I tried to reset configuration and do nothing, sector written remain the same for more than an hour. But when I reconfig hotspot, dhcp client for wan, dhcp server for hotspot interface, radius + user manager, no connected client at all, the written sectors start rising again about 30 sectors every 2-3 seconds.
So, my question is: IF I continue to use CF, when some clients connected, running, how long my CF can stand? Thanks.

Thanks for your post.
I experienced a high CPU load when users logged in on the hotspot. While googling on this I came across your post.
I compared the disk writes with my other ROS 5.24 server and cam to the same conclusion.

Server 1: ROS 5.24 / 119 days online / 8 mill. sector writes
Server 2: ROS 5.26 / 2 days online / 6 mill. sector writes

Thanks, M

Well here’s the latest update:

Overall calculation: 1 day = 1 millions write. 365 days = throw off NAND Flash lol
About your high CPU load, Hotspot and Wireless requires alot of CPU resources. Combine both in a system resulting high CPU load.
That’s why I prefer to use x86 Mikrotik OS as Hotspot Server, output to managed switch, then use standalone wireless access points.
