I am building a home TrueNAS server mainly for cold storage, and also for a basic VM for archiving/datahoarding tools, and possibly for jellyfin. It will be running 6 14 TB drives in RAIDZ2, and will be spinning down the drives after they have not been used for a while.
I’ve decided to go with the Ryzen 7 Pro 4750G (and throw in an Arc A380 later if needed) for the ECC support and low idle power. Since I require 6 sata connectors for the 6 drives, the Asrock B550M Pro4 qualifies, also supports ECC memory, and is a micro ATX board so it will have less idle power draw. It seems like a good choice (besides the Realteck LAN).
But since learning about ASPM and other power saving options refinements, some people seem to have gotten better idle consumption with ASUS boards. I’m not sure if that is simply because in the tests they have less hard drives, or if the difference did exist if it still does. So if someone could shed light on the differences in idle power between AsRock and Asus boards that would be great, and whether it would be significant enough to get an Asus board with an M.2/PCiE adapter/HBA to get more sata ports since Asus seems to cap out at 4 with their budget options.
If you look at this spreadsheet: -Die sparsamsten Systeme (<30W Idle)- - Google Sheets from [Sammelthread] - Die sparsamsten Systeme (<30W Idle) | Hardwareluxx , it seems at the time of posting the ASRock board couldn’t get past the C3 state while the ASUS boards could reach the C6 state.
If you could recommend a budget motherboard/pcie sata expansion option for low C state idle power that supports ECC RAM that would be great.
