ProGrade Digital SDXC UHS-II V90 Memory Card (128GB, 2-Pack)

The V90 UHS-II SDXC Memory Card from ProGrade Digital features a storage capacity of 128GB 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, 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 support 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. Built for extreme conditions, ProGrade Digital's UHS-II SDXC V90 Memory Card can withstand temperatures from -13 to 185-degree-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.
