The ProGrade Digital 128GB UHS-II SDXC V90 Memory Card supports read speeds of 300 MB/s and write speeds of 250 MB/s. It has a V90 Video Speed Class rating, ensuring minimum write speeds of 90 MB/s, making it suitable for use in DSLRs, mirrorless cameras, camcorders, and digital cinema cameras for rich data streams, high bit rate MPEG-4 video, 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 128GB UHS-II SDXC Memory Card 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.
