I just wanted to report that I am running my Rock 5B 8Gb now in my production environment with:
Armbian 22.11.2 Jammy
boot from SD Card
Os on SSD via PCI M2 E Key Sata adapter
Sonoff Zigbee 3.0 USB Stick
Case: case by Cyborgium at Thingiverse
1000Mbit Ethernet connection
5V 3A power Adpater (official RASPI4 power supply)
Radxa Rock5b Fan with heatsink
Running:
Nextcloud snap NC25
Iobroker
wireguard
radxa fan control
idle Power draw: 2,4 watt
Replaced Raspberry Pi 4 8Gb. High performance increase. Downloads from local NC install +100MB/s (might be higher if using 2,5 GBit Ethernet). RP4= 30MB/s.
Fan never spins, only when benchmarking, Idle temp 37 C
