The 64GB Professional 1667x UHS-II SDXC Memory Card from Lexar features a storage capacity of 64GB 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. This card is also well-suited for video capture, including 4K, 3D, and Full HD video, and can achieve maximum read speeds of up to 250 MB/s and maximum write speeds of up to 120 MB/s. Thanks to its V60 speed class rating, minimum write speeds are guaranteed not to drop below 60 MB/s.

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.

To help protect against accidental file deletion, there is a built-in write protect switch. To further safeguard against possible data loss, users can download free Image Rescue software that is designed to recover most photo and video files.
