Designed for high bit depths, frame rates, and resolutions, including Full HD, 4K+, and 3D video, as well as raw and continuous burst photography in DSLR and drone systems, the 64GB AV Pro Mk 2 UHS-II SDXC Memory Card from Angelbird features a storage capacity of 64GB and takes advantage of the UHS-II bus to support sustained read speeds of 280 MB/s and sustained write speeds of 260 MB/s, as well as sequential read speeds of 300 MB/s and sequential write speeds of 280 MB/s. This card has also been designed with the V90 Video Speed Class rating, which guarantees minimum write speeds of 90 MB/s. UHS-II media achieves its speed through an extra row of pins and while this card has been designed for cameras that are UHS-II / V90 compatible, it may be used in devices that do not support UHS-II / V90.

However, bear in mind that this card will then default to your device's speed class and bus rating, 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 does not support U3, this card is compatible with the U1 and Class 10 standards, each of which guarantees minimum write speeds of 10 MB/s.
