PNY SDHC card Elite UHS-I U1 16 GB

UHS-capable SD cards allow theoretical data speeds of up to 104 MB / s. The speed class is specified as U1 or U3: U1 for full HD videos - and U3 for 4K videos. Memory cards with support for UHS-I are backwards compatible and can be used in devices without UHS support (with limited power).

The Speed Class provides information about the minimum, continuous data transfer when writing video files to a memory card. The speed class number indicates the transmission rate in megabytes per second. Class 2 cards are designed for a minimum, continuous transfer rate of 2 MB / s and Class 10 for a minimum, continuous transfer rate of 10 MB / s. The speed class is divided into classes 2, 4, 6 and 10. For Full HD video (1080p) at least Class 6 is recommended.
