SANDISK Extreme PRO UHS-I V30

The powerful SD UHS-I memory card opens up creative possibilities for you. With a recording speed of up to 140 MB/s and UHS Speed Class (U3), it enables stunning and lag-free videos in high-resolution 4K UHD. For fast post-production immediately after the photo shoot, the card achieves a transfer speed of up to 200 MB/s. Additionally, the memory card is resistant to weather, water, shocks, and other hazards, allowing you to use it worry-free anywhere.

The Speed Class indicates the minimum continuous data transfer rate when writing video files to a memory card. The Speed Class number shows the transfer 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 classes are divided into classes 2, 4, 6, and 10. For Full HD video (1080p), a minimum of Class 6 is recommended.

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

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