Memory cards

A memory card is chosen first according to the device it goes into: full-size for most cameras, micro for phones, drones and handheld consoles. For video, the sustained write speed guaranteed by its speed class prevents recordings from cutting out. Dash cams and security cameras need a card designed for constant writing. The advertised read speed matters much less.
