Putting the Secure in Secure Digital. These Angelbird SDXC 256GB AV Pro Mk2 UHS-II V90 memory cards provide fast write speeds in a heavy-duty SD casing. Angelbird touts these cards as waterproof, shockproof, magnet-proof, x-ray proof, and capable of withstanding temperatures between -13 and 185°F, meaning you can use them in harsh environments such as deserts and snow. A built-in write-protect switch helps keep your content from getting deleted.

V90, UHS-II, SDXC Memory Card. This UHS-II SD card is capable of write speeds up to 280 MB/s. This grants the card a V90 rating for high-resolution, high-bitrate video capture from cameras like the Panasonic GH5S, Fuji X-T3, Panasonic EVA1, Blackmagic URSA Mini Pro, and Blackmagic Pocket Cinema Camera 4K.

Other Features. This UHS-II card is backward compatible with UHS-I cameras but will only provide a write speed of 90 MB/s which is often not enough for 4K capture. If you have specific camera write-speed requirements, feel free to reach out for our recommendation.
