Here is my n=1 study: With every generation of the Raspberry Pi, from the first onward, up until the RPi4, I had been very successful destroying my SD-Cards (also the mentioned SanDisk Extreme), USB-Sticks and even SSDs. The SSD lasted a bit more than two years. The only time the storage didn't get corrupted, was when I mounted / on a nfs file syste on my NAS. But this was only an episode of a couple of months, most of the SD cards also survived such a time span.
A couple of months ago I abandoned the RPi for a Zotac ZBOX with a data center grade SSD. Time will tell, if this choice will last. [email protected] schrieb am Dienstag, 3.
