Running unraid beta 25 on the Odroid h2+ for several days now. Installed several docker containers (pihole, nextcloud, unifi controller, bookstack, bitwarden, nginxproxymanager, duplicacy)... needs around 3W with one active M2 SSD (Adata 8200 xpg), the HDD (WD Red 3 TB) is not active. 8 GB RAM with approx 40% utilisation.
Performance? enough.
Power consumption? great.
I pinned the H2+ and the HDD to a wall, so quite invisible as well
