SanDisk Extreme

High speed for your recordings. UHS Video Speed Class 30 (V30) and UHS Speed Class 3 (U3) enable the recording of high-resolution 4K UHD videos. Available in storage capacities from 32 GB to 256 GB and with read speeds of up to 90 MB/s for fast data transfers. The cards are compatible with SDHC and SDXC capable devices.

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 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.

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), Class 6 is recommended at a minimum.

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 supporting UHS-I are backward compatible and can be used in devices without UHS support (with limited performance).
