I had a 500 GB SSD used as cache on my NAS but the estimated lifespan was going too down so I’ve replaced it.
Now I’m using the SSD in an USB enclosure attached to Raspberry Pi 4 to boot Astroberry, but due to low estimated lifespan (1%), (and because I don’t know where to store the Astroberry microSD without loosing it :) ) I’ve set the microSD as fallback.
Here how I’ve made it.
