I’ve never used TrueNAS before and dived to many times into it to fix HexOS bugs, but it’s Beta software so I wont complain.
Hardware
This is what I use (a bunch of old Hardware laying around) and it’s probably not the smartest config.
- Corsair 500 W PSU (too much, but cheap)
- ASUS PRIME B450M-A II (mATX) (Fine!)
- AMD Ryzen 3 2200G (no GPU required)
- 2x 8 GB G.Skill Aegis (no OC for stability)
- Noname Realtek RTL8125 2.5 Gb Ethernet Card
- Akyga AK35BK case (screwing things in sucks but the rest is fine for the price)
- A boot SSD (on the back) and two WD Red Pro 4TB 3.5″ (bottom and front) for the pool
- No extra case fans. I have two open PCI-E slot covers (from a GPU) where fresh air comes in and exhausts through the PSU on top. CPU and HDD temps are (idle) between 30-40° C.
BIOS Settings
I would recommend these options:
- Boot → Secure Boot → OS Type [Other OS) to disable it
- Advanced → CPU Configuration → SVM Mode [Enabled] for Virtualization
- Advanced → APM Configuration → Power On By PCI-E [Enabled] for Wake on LAN
- Boot → Boot Configuration → Wait for F1 if Error [Disabled] because missing Keyboard/GPU
Shutdown and Wake on LAN
I live in a place with high power cost and turning it off when I’m not at home or sleeping makes sense. I know the drives don’t like that but If one fails, thats what the second is for, right?
Shutdown
Setup a CRON Job with the command:
/sbin/shutdown -P
Wake on LAN
- Search the name of your network adapter on the HexOS Dashboard
- Go into System –> Shell
- Give yourself admin rights with:
sudo -i
Then paste your truenas_admin passwort with CTRL+Shift+V - Activate Wake on LAN on your Network device with:
ethtool -s [adaptername] wol g - Check with
ethtool [adaptername]
if Wake-on is g
More ideas
Your NAS should now react to Magic Packets but it might „forgets“ this setting, so someone suggested Init/Shutdown Scripts
A good tool on Windows to send wake ups is NirSoft’s WakeMeOnLAN commands
Power saving
First, move the System Data Set to the boot-drive (System –> Advanced Settings –> Storage –> Configure). Else, every few minutes, something would be written on the HDD’s and they wouldn’t go into standby.
But now the 25.10 problem: They removed S.M.A.R.T settings.

Some thing to explore
- Can I use my boot SSD for other things? Its too large just for a bit of NAS software.
- One power saving solution was to disable SMART and run it on startup with a script
Do the device names change on every startup?! Looks like, so my SMART scipts didn’t make sense. smartctl -n standby -t short /dev/sdx
