My understanding is that SD cards have a certain write count before they fail (or require a reformat), and that eMMC doesn't. Or that the number of writes before failure is much higher. Is that not correct? Regardless, I understand that hardware dies. But generally speaking I'd like to be able to deploy a single board system and not have to worry about having to physically maintain it unless it literally fails for some reason.
