I have deployed industrial microSD cards, swissbit offers some for which you can choose if they should run the flash cells as mlc or slc trading capacity for endurance. When you deploy some controller module in a water pumping station in a mountain, you gladly pay 25€ for a better card to make sure you don't have to fly out a technician who knows what to do to restore that module because the flash thing failed because of logging data. SD card flash quality and specs are a huge rabbit hole, no info about tlc/qlc or static/dynamic wear leveling is available for consumer cards, its pretty annoying.
