Designed for 8K and 4K video, as well as raw and sequential burst photos, the 256GB X-PRO 90 UHS-II SDXC Memory Card from PNY Technologies provides up to 256GB of storage for DSLR, mirrorless, and advanced video cameras. It takes advantage of the UHS-II bus to deliver read speeds of up to 300 MB/s and write speeds of up to 280 MB/s. Thanks to its V90 speed class rating, minimum read and write speeds are guaranteed not to drop below 90 MB/s.
Please note that to achieve the full potential of this card's read and write speeds, it must be used in devices that support UHS-II. While it may be used in devices that only support UHS-I, read and write speeds will be slower.
