The SanDisk 256GB Extreme PRO UHS-I card offers high read/write performance and rugged durability, making it suitable for 4K video and burst photography. Its lifetime warranty and RescuePRO software add value, though the UHS-I interface caps ultimate speed potential.

The Lexar 256 GB Professional Silver SD Card is a high-capacity, UHS-I card delivering up to 205 MB/s read and 140 MB/s write speeds with V30 video rating and robust durability. It targets enthusiast photographers and videographers who need fast transfers and rugged protection, but it lacks UHS-II performance.
