Tested and approved to capture Full HD, 4K, and 6K raw video, the 128GB AV Pro UHS-II microSDXC Memory Card from Angelbird is designed for drones, actions cam POV recording, camera systems, game consoles, and more. It features a storage capacity of 128GB 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, as well as sequential read speeds of 280 MB/s and sequential write speeds of 160 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 / 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. Aside from support for UHS-II, V60, and U3, Angelbird also built this card with support for the Application Performance Class 1 (A1) spec, which includes optimizations to give Android users an improved mobile experience, delivering faster mobile app performance. The A1 spec allows the card to manage random read input-output access per second (IOPS) operations, so it can quickly open apps and process accompanying tasks, such as audio, graphics, saved profiles, and in-app permissions. Built for extreme conditions, Angelbird's 128GB AV Pro UHS-II microSDXC 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. Thanks to an included UHS-II microSD to SD adapter, you'll be able to use this card to be used in SD-compatible devices. The AV Pro is protected by a limited 3-year warranty. However, to receive the full limited warranty, this product must be registered on the Angelbird Personal Service Portal within 30 days after purchase using the included activation code. If not registered within this period, the market-specific legal guarantee period comes into force.
