I've now nuked and paved my #RaspberryPi 4B for the 4th time. By now I've learnt from experience that SDs aren't meant to last holding the entire filesystem. After another case of "Segmentation fault" (likely corrupted SD), I've moved the filesystem to a USB. Depending on performance, I may reattempt moving everything to a partition of a 1TB HDD being used primarily for #Plex.

Wow, that's impressive it's lasted so long running 24/7 (presumably with constant read/write for logs, journal etc?) Mine is just running a Plex server and Pi-hole. Swap was always turned off too, but after every new install I found it took a few weeks before I got Segmentation Faults. I've now moved the filesystem to a 400GB HDD partition, so fingers crossed I should have no more issues.
