The 512GB UHS-II SDXC Memory Card (2-Pack) from ProGrade Digital features a storage capacity of 512GB per card and takes advantage of the UHS-II bus to support maximum read speeds of 300 MB/s and maximum write speeds of 250 MB/s. This card has also been designed with the V90 Video Speed Class rating, which guarantees minimum write speeds of at least 90 MB/s, allowing the card to be used in DSLRs, mirrorless cameras, camcorders, and digital cinema cameras that produce rich data streams, including 6K, 5K, 4K, UHD 4K, and high bit rate MPEG-4 video. It is also well-suited for raw photos and rapid-fire bursts.

UHS-II cards achieve their 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 guarantee minimum write speeds of 10 MB/s.

Built for extreme conditions, ProGrade Digital's 512GB UHS-II SDXC Memory Card (2-Pack) is able to withstand temperatures from -13 to 185°F, allowing you to take this card with you into extreme environments, such as snow and deserts. It is also shockproof and X-ray proof, and a built-in write protect switch helps to safeguard your content from being erased.

Please note that this 2-pack cannot be used with the Black Magic Pocket Cinema 6K to capture 6K ProRes video at 120 fps or BlackMagic RAW at 60 fps.
