It's actually weird that Raspberry Pis seem so bad at using SD cards.

I've just scrapped a large PBX which had a whopping 8MB SD card in it. Its 486 processor booted Linux off the SD card, it wrote CDRs to the SD card, it served said CDRs up over a web interface off it, it saved its logs to the card, and all the other day-to-day chatter of a running system.

It was installed pretty much 20 years ago. The date sticker on the SD card shows that it was replaced 18 years ago, presumably as part of an upgrade.

I'm going to guess that it was not a normal COTS SD card, and instead designed for continuous writes.

The 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.

Because of a properly configured, boot disk. Just boots once per power cycle.

Meanwhile 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. Rebooting it was a big deal though, so that rarely happened.
