The Angelbird 256GB AV Pro UHS-II microSDXC Memory Card is designed for drones, action cam POV recording, camera systems, game consoles, and more, and has been tested and authorized to capture Full HD, 4K, and 6K raw footage. It has a storage capacity of 256GB and uses the UHS-II interface to provide sustained read rates of 260 MB/s and sustained write speeds of 140 MB/s, as well as a sequential read and write speeds of 280 MB/s and 160 MB/s, respectively. This card also has the V60 Video Speed Class rating, which assures minimum write rates of 60 megabytes per second.
While this card has been intended for cameras that are UHS-II / V90 compatible, it may also be used in devices that do not support UHS-II / V90. Keep in mind, however, that this card will default to the speed class and bus rating of your device, such as UHS-II and V60, which supports minimum write speeds of 60 MB/s, UHS-II and V30, which supports minimum write speeds of 30 MB/s, or UHS-I and U3, which also supports minimum write speeds of 30 MB/s. If your device doesn't support U3, this card is also compatible with U1 and Class 10, both of which guarantee minimum write rates of 10 MB/s.
