Designed for 4K Ultra HD videography, high-res photography, and more, the 128GB Elite-X UHS-I SDXC Memory Card from PNY Technologies provides up to 128GB of space for capturing 4K UHD and Full HD 1080p video, plus raw and JPEG still and burst images. It is compatible with the UHS-I bus and features a speed class rating of V30, which guarantees that write speeds won't drop below 30 MB/s. If your camera doesn't support V30, this card also supports U1 / Class 10, both of which guarantee minimum write speeds of 10 MB/s. Additionally, read speeds are supported up to 100 MB/s.
