I'm planning to run the jussi for my API node on a Raspberry Pi 4 with 4Gb RAM and SD card.
Is this sufficient in your view or should I add a SSD on USB?
I have both the cable and SSD drive but understood jussi just used RAM for cache and didn't really do IO.
It will mostly be cpu/ram so I don't see a huge difference /w SD vs SSD outside of management time (and reliability on power outages as SD corrupt easier).
You can get a 250G SSD and cable for around $40.
