The Samsung 256GB SDXC UHS-I MB-SD256SB/WW is a high-capacity memory card designed for devices that accept SDXC format and UHS-I interface. With 256 GB of storage and sustained transfer rates, it supports high-resolution photo capture and full HD or 4K video recording. The card's durable construction provides protection against drops, shocks, magnets, water, X-rays and extreme temperatures, helping to safeguard stored files during everyday use and travel.

Advantages

This memory card offers fast sequential read speeds up to 180 MB/s and write speeds up to 130 MB/s, enabling quick file transfer and efficient recording of high-bitrate video. Rated UHS Speed Class 3 (U3) and Video Speed Class V30, it meets the minimum sustained write performance required for continuous 4K recording. The compact SDXC form factor and a white casing simplify device compatibility and handling while the lightweight design adds negligible bulk to cameras or portable devices.
