SanDisk SDXC Extreme PRO - 128 GB, 300 MB/s, C10, UHS-II, U3 V90. This card features a storage capacity of 128GB and takes advantage of the UHS-II bus to support read speeds of up to 300 MB/s and write speeds of up to 260 MB/s. Thanks to the V90 Video Speed Class rating, write speeds are guaranteed not to drop below 90 MB/s.

UHS-II media achieves its 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 guarantees minimum write speeds of 10 MB/s.

Built for extreme conditions, SanDisk's 128GB Extreme PRO UHS-II SDXC Memory Card is protected against shock, temperatures, x-rays, and water. Also featured is a built-in write-protect switch that helps to safeguard your content from being erased.
