I'm going to guess that it was not a normal COTS SD card, and instead designed for continuous writes.
replyThe factors for SD card failures in raspberry pi seem to be mostly SD cards not meant for the purpose and having things like swap, atime or disk logs enabled which leads to unnecessary writes.
It just appears to be a pretty standard Sandisk SD card.
replyBecause of a properly configured, boot disk. Just boots once per power cycle.
replyMeanwhile something like the pi, on most images, is writing logs to the storage CONSTANTLY. Not to mention is regularly booted.
This was constantly writing to the SD card. It was the only storage on the device.
replyRebooting it was a big deal though, so that rarely happened.
