Transcend 500S MLC microSD Memory Card with Adapter, UHS-I, 8GB–32GB

MLC NAND rather than the TLC used in consumer cards, which is the reason to pay for it: MLC tolerates far more write cycles, so this suits logging, embedded gear and surveillance rigs that overwrite the same blocks continuously.

Capacities top out at 32GB here, so it is a duty-cycle choice, not a capacity one. For loop recording at higher capacity, the Transcend UHS-I U1 Micro SD Memory Card with Adapter is the high-endurance 350V line.
