I like to have my Nas on 24/7, though I would like to reduce costs due to not needing much power most of the day. I've seen youtubes using the bios to reduce in the powerplan 1 un2 15 watts, can anyone share more info on this ?

Got a F4-424max, 2x m.2 ssd, and a raid5 with 4x HDD, < last set to turn off after a few minutes. Essentials on m.2 evading electricity use.

Would a too low ppl 1 give problems, or will it skip directly to ppl 2 ?

We understand your need to save power, but being too aggressive isn't necessarily a good thing.
If you push PL1 too aggressively (example 8–10W on your system):

You may see:
Slow file transfers
Web UI lag (TOS interface delay)
RAID rebuild taking much longer
Docker / Plex stuttering under load
CPU stuck at very low clocks (0.8–1.2 GHz range)

Recommended PL settings for your NAS

For stability + efficiency balance:
Safe low-power tuning
PL1: 12–15W
PL2: 25–35W

This setting helps:
very low idle cost
still smooth NAS experience

Ok, will try in the weekend, gotta get it in another room.

Thanks
