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 MK2 UHS-II SDXC Memory Card (2-Pack) from Angelbird features a storage capacity of 64GB and takes advantage of the UHS-II bus to support sustained read speeds of 260 MB/s and sustained write speeds of 140 MB/s. This card has also been designed with the V60 Video Speed Class rating, which guarantees minimum write speeds of 60 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 / V60 compatible, it may be used in devices that do not support UHS-II / V60.

However, bear in mind that this card will then default to your device's speed class and bus rating, such as 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.
