Comment on What is your self hosted power draw?

My NAS/home server takes about 180 kWH/year, or 20W on average (costs me about 5 Euro/month). This feels like a lot to me and makes up a good chunk of my total energy usage.
What I did to optimize it is mostly select a “low-power” x86 platform, and limit the number of disks. I also decided not to use TrueNAS because it couldn’t let the disks from going to sleep.
The machine hosts 10 TB of usable storage (+RAID 1), syncthing, immich, file server, Influx DB, Grafana, and a few other services.
That’s the one thing I don’t like about Truenas. It technically can spin down disks, but there’s no way to force them. You can set the idle timer to 5 minutes, but then it constantly spins them back up again. Now I just power the entire system down with home assistant outside of the usage hours and I can power it up again with home assistant using wake on Lan.
A bit goofy, but it works for me

Yeah I use Unraid for multiple reasons but being able to spin down disks when not in use was a big factor. I have 6 mechanical drives totalling 56TB of usuable storage so it was important to me they don’t all need to be on at the same time. TrueNAS also comes with some other headaches, I like being able to drop in whatever disk I need to for expansion or replacement.

I didn’t move that far away (to Debian + ZFS), so that limitation still remains. Although the addition of Raid-Z expansion should alleviate things quite a bit.
