> do not try to run Raspberry Pi from SD cards in "production" under any circumstances on a large scale Can't confirm. I've written about this before, but I'm mainly responsible for running the https://info-beamer.com digital signage service. It's using a custom Linux distribution that always boots into an R/O system. All user content is on a separate partition that can always be restored if there's any error. The ext4 fs is tuned in a way that the kernel defers writes quite a while to minimize write access if possible. Since customers purchase their own SD cards, we have limited control of what ends up in a device. I've seen exactly one SD card related problem thus far. There are devices that have been running >3 years 24/7, so it's doable. But you can't just use Raspbian. You have to properly design the system. |
