The Angelbird 512GB AV Pro MK2 UHS-II SDXC Memory Card is engineered for high bit depths, frame rates, and resolutions, making it ideal for Full HD, 4K+, and 3D video, as well as raw and continuous burst photography in DSLR and drone systems. With a storage capacity of 512GB, this memory card utilizes the UHS-II bus to deliver impressive sustained read speeds of up to 280 MB/s and sustained write speeds of 260 MB/s, along with maximum read speeds of 300 MB/s and maximum write speeds of 280 MB/s. Additionally, it is rated with the V90 Video Speed Class, ensuring that write speeds remain consistently above 90 MB/s. UHS-II media achieves speed through extra pins. If used in a non-UHS-II/V90 device, it defaults to the device’s speed class and bus rating, with minimum write speeds ranging from 10 MB/s to 60 MB/s.
