I know this topic has been covered many times but maybe never solved.
Fresh install
Moved system dataset to boot pool
No jails, VMs, nothing running
No GUI
Tried rebooting many times
SMART off
Dedub off
There is constant and equal pattern of writing to the disks, the noise they produce is always the same (same pattern) and the IO GFX shows the same pattern every few seconds.
It looks like Python keeps generating disk IO, here is the result by using most CPU time:
322 - S 1:20.15 python3.9: middlewared (python3.9)

I love TrueNAS, best FreeBSD solution. Not an hardcore NAS user hence this constant disk activity (and energy consumption), will move me away from it…
