This is for the ETH2 validator. (Yes, life is at stake.) I've tried this with a Zheino SSD with no luck (probably too cheap). Dogfish 1TB works fine. I've had success using the Geekworm X850 for a tiny Raspberry Pi bitcoin node that's been running for over 1 year, so I wanted to try it for ETH2 as well. The photos already have an X857 in a geekworm case, but the second shows the USB3.1 connector going from the X857 to the Pi. Screenshot of Grafana with Prometheus for advanced device monitoring at both physical level (e.g. temperature level, disk writes, etc.) and performance level (e.g. disk IOPps).
