The 256GB UHS-II microSDXC Memory Card with SD Adapter from ProGrade Digital features a storage capacity of 256GB and takes advantage of the UHS-II bus to support maximum read speeds of 250 MB/s and maximum write speeds of 130 MB/s. This card has also been designed with the V60 Video Speed Class rating, which guarantees minimum write speeds of at least 60 MB/s, allowing the card to be optimized for 4K, UHD, Full HD, and 3D video captures, as well as 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 / V60 compatible, it may be used in devices that do not support UHS-II / V60. However, bear in mind that this card will then default to your device’s speed class and bus rating, such as 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 256GB UHS-II microSDXC Memory Card with SD Adapter 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 resistant against x-rays and shock. Included is a microSD to SD adapter, which allows this card to be used in devices with full-sized SD slots.
