Designed to handle high bit depths, frame rates, and resolutions, including Full HD, 4K+ raw, and 3D video, as well as raw and continuous burst photography in DSLR and drone systems, the AV Pro MK2 UHS-II SDXC Memory Card from Angelbird offers a storage capacity. It utilises the UHS-II bus to deliver maximum read speeds of 280 MB/s and maximum write speeds of 160 MB/s, with sustained read speeds of 260 MB/s and sustained write speeds of 140 MB/s (V60). It 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 maximum read speeds of 300 MB/s and maximum write speeds of 280 MB/s(V90). With a V60/V90 Video Speed Class rating, this card ensures minimum write speeds of 60 MB/s and 90 MB/s. UHS-II media achieves its speed through an extra row of pins and while this card can be used with cameras that are UHS-II / V60 compatible, it may also be used in devices that do not support UHS-II / V60 and 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 V30/V60, which supports minimum write speeds of 30 MB/s(V60) and 60 MB/s(V90), 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. Built for extreme conditions, Angelbird's AV Pro MK2 UHS-II SDXC Memory Card is protected against water, shock, x-rays, magnets, and temperatures ranging from -13 to 185°F. Also featured is ECC data reliability, wear leveling, and power management for low power usage. A built-in write protect switch helps safeguard your content from being erased.
