Our take on the SanDisk SDSDXXD-512G-GN4IN

The SanDisk Extreme PRO SDXC UHS-I card is a 512GB memory card for cameras that record high-bitrate photos and video. It is rated for UHS-I speeds up to 200MB/s read and 140MB/s write, with V30 and U3 ratings that suit 4K video and burst shooting. It sits above the plain Extreme line, which is slower, and below UHS-II cards like the SanDisk Extreme PRO UHS-II, which cost more and need a UHS-II slot to pay off. Owners pick it for reliable write speed in DSLRs and mirrorless bodies without moving to a pricier standard.
