Lexar Professional 633x SDHC/SDXC UHS-I cards let you quickly capture and transfer high-quality photos and 1080p full-HD, 3D, and 4K video, with a read transfer speed up to 633x (95MB/s). The cards leverage UHS-I technology (U1 or U3, depending on capacity) for high-speed, Class 10 performance. And when using a USB 3.0 card reader, you’ll power through post-production with high-speed card-to-computer file transfer. This dramatically accelerates workflow from start to finish, so you can save time and get back to the business of photography. Cards come with a limited lifetime warranty.
