The 64GB SF-G Tough Series UHS-II SDXC Memory Card from Sony 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 8K, 4K XAVC S, 60p AVCHD, 3D, HFR, and Full HD video, and can achieve maximum read speeds of up to 300 MB/s and maximum write speeds of up to 299 MB/s. Thanks to its V90 speed class rating, minimum 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.
