It can be just the one I’m using at home, with Home Assistant installed, which is doing a lot of R/W operations every second.
It just seemed to be a more robust and easier/nicer to «wrap» in a 3D printed case, by just using a SSD expansion board instead of having all these USB things connected.
We will (however) not use HA in all the properties. Just MQTT every sensor data to a centrally located server. So an SD card is maybe suitable in this case, with Ubuntu Core.
Just booted the Ubuntu Server 20.10 image from the SSD. Works great. But I’ve grown found of Snaps and Ubuntu Core the past year working with it - so I’m still having my fingers crossed from a fix ;D
