UHS Speed Class refers to Ultra High Speed. The numbers represent the megabytes per seconds that can be written to the card. Speed Class can currently be 2, 4, 6 and 10. These classes indicate the minimum write speed required to ensure smooth, continuous video recording. They are Speed Class, UHS Speed Class, and Video Speed Class. There are three types of speed classifications used for video. In some cases, the recording may even stop altogether while the card catches up with the camera.
