The ProGrade Digital MicroSDXC Memory Card with Adapter in Gold has a storage capacity of 256GB and supports read speeds up to 250 MB/s and write speeds up to 130 MB/s. It also features the V60 Video Speed Class rating for optimized performance in capturing 4K, UHD, Full HD, and 3D videos, 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 guarantees minimum write speeds of 10 MB/s.

Built for extreme conditions, ProGrade Digital's 256GB UHS-II microSDXC Memory Card with SD Adapter can 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 to X-rays and shock. A microSD to SD adapter is included, allowing this card to be used in devices with full-sized SD slots.
