Designed for sports camcorders, tablets, and smartphones, the 64GB Professional 1800x UHS-II microSDXC Memory Card from Lexar features a storage capacity of 64GB and supports maximum read speeds of up to 270 MB/s and maximum write speeds of up to 150 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. All of this allows for users to immerse themselves in extreme sports videography and photography in 4K, Full HD, and 3D.
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.
