I’m responsible for a fleet of a few hundred Raspberry Pis being used as home monitoring hubs - they use high grade SD cards, and are configured to write as little as possible while still fulfilling their function, yet we still see one or two a month fall of the internet because of SD card corruption. This is absolutely a problem. I believe the compute module is somewhat better in that it uses eMMC rather than SD cards.

Correct me if I’m mistaken, but isn’t eMMC literally just an embedded SD card?

  It is, and it is better because it probably has better chips, but it will die, and brick RPi in the future.

  As someone who has also worked with fleets of devices (R.Pi-based and others) working off SD-cards, I can confirm what jon-wood is saying. For some reason SD cards fail at a much higher rate than eMMC flash chips in traditional SMT packages.

  Same interface as an SD card, but better firmware and probably higher quality flash. SD cards are really aggressively cost-cut, often coming in than less than the price of raw flash of the same capacity.
