>All microSD cards have a high failure rate.
You can buy genuinely reliable microSD cards, if you really need them. Delkin, Innodisk, Swissbit and others make industrial microSD cards with SLC flash, ECC, SMART and power loss protection. Capacities are small and you'll pay a steep premium, but they legitimately have endurance and MTBFs that compete with conventional SSDs.
- crispyambulance 2y agoThis is true. You can get "industrial" versions of these cards that are intended to be used as BOM items for products. This means you get a stable supply and they won't change the part number out from under you (which happens even with reputable suppliers when you buy as a consumer). When they're about to EOL the part, you get a heads-up multiple months in advance and a "last time buy" opportunity. In my experience, these aren't "better" performance-wise. You just "know" what you're getting, have an opportunity to qualify it, and you won't get surprise changes. Of course, the price is jacked up as a result. Generally speaking, it's usually better to make the customer responsible for the SD card if you have to use one at all.
