Adata microSDXC card High Endurance 256 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.

Optimized for apps, this card delivers fast startup and more power for your mobile applications. The App Performance Class is especially important for SD cards, which are used in smartphones and tablets. The A2 icon indicates that the SD card meets the requirements of the applicable App Performance Class 2 (A2): At least 4000/2000 IOPS for random and at least 10 MB / s for sequential transfers.

The Video Speed Class covers 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 Video Speed Class tags and an SD memory card with the same Video Speed Class tag, 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.
