The ADATA Speed Plus 256GB microSDXC UHS-I U3 (UD256GUI3V30A2SP-RA1) is a high-capacity memory card designed for devices that require fast sustained performance, such as drones, action cameras, 360° cameras and mobile devices. It delivers up to 180 MB/s read speed and up to 160 MB/s write speed, supports the V30 video speed class for 4K recording and meets the A2 application performance class for improved app responsiveness and multitasking.

Advantages

This microSDXC card combines high sequential transfer rates with A2-class random IOPS for faster app loading and smoother multi-command handling. It conforms to UHS-I U3 and V30 standards to ensure stable minimum write speeds suitable for Full HD and 4K video capture. Built-in LDPC error correction and multiple durability tests (waterproof, shockproof, X-ray proof, anti-static, and temperature resistance) provide reliable data protection in demanding environments.

How to use

Insert the microSDXC card into a compatible device or into an adapter for standard SD slots. Format the card in the host device before first use to ensure file system compatibility and optimal performance. For recording high-resolution video, select the device’s appropriate recording mode (e.g., 4K) and verify free capacity and available write speed. Use the card with devices that support UHS-I and the V30/U3 classes to achieve rated performance.

Recommendations

For reliable 4K or continuous burst shooting, periodically transfer important files to a separate storage medium and avoid filling the card completely. Format the card in the device where it will be used and keep firmware of host devices updated to maintain compatibility and performance.
