UHS-I bus system

UHS-I capable SD cards enable theoretical datatransfer 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 compatible and can be used in devices without UHS support (with limited performance).

Video Speed Class

The Video Speed Class includes the five speed levels V6, V10, V30, V60 and V90, where the number indicates the minimum write rate in megabytes per second (MB/s). By combining a device with a Video Speed Class rating and an SD memory card with the same Video Speed Class rating, you can capture the best quality memories. The fastest options, V60 and V90, support 8K resolution, while V6, V10 and V30 reliably capture Full HD and 4K resolution.

Speedclass 10

The Speed Class indicates the minimum continuous data transfer rate when writing video files to a memory card. The Speed Class number indicates the transfer rate in megabytes per second. Class 2 cards are designed for a minimum continuous ¨btragungsrate of 2 MB/s and Class 10 for a minimum continuous ¨btragungsrate 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.
