Lexar Professional 2000x SDHC/SDXC UHS-II 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 2000x (300MB/s). The cards leverage UHS-II technology (UHS Speed Class 3 (U3)) for high-speed performance. And with the included SD UHS-II 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. These cards also come with a limited lifetime product support.
