The 128GB Professional 2000x UHS-II SDXC Memory Card (2-Pack) from Lexar features a storage capacity of 128GB per card and takes advantage of the UHS-II bus to support advanced DSLR functions such as continuous shutter bursts and rapid shooting, as well as raw and JPEG captures. These cards are also well-suited for video capture, including 4K, 3D, and Full HD video, and can achieve maximum read speeds of up to 300 MB/s and maximum write speeds of up to 260 MB/s. Thanks to their V90 speed class rating, minimum write speeds are guaranteed not to drop below 90 MB/s.
UHS-II cards achieve their speed through an extra row of pins, and while these cards have been designed for cameras that are UHS-II / V90 compatible, they may be used in devices that do not support UHS-II / V90. However, bear in mind that these cards 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, these cards are compatible with the U1 and Class 10 standards, each of which guarantee minimum write speeds of 10 MB/s.
As with most Lexar media, these memory cards are able to withstand temperatures from -13 to 185°F, allowing you to take them with you into extreme environments, such as snow and deserts. Should the cards become compromised, users in the Americas will benefit from a limited lifetime warranty, while those in Germany and regions not recognizing the lifetime warranty will benefit from a limited 10-year warranty.
