The 64GB SF-M/T2 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 4K, 3D, HFR, and Full HD video, and can achieve maximum read speeds of up to 277 MB/s and maximum write speeds of up to 150 MB/s. Thanks to its V60 speed class rating, minimum write speeds are guaranteed not to drop below 60 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 / 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 or U3, or UHS-I and V30 or U3, both of which support 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. If used in a UHS-I device, this card’s read speeds will reach 95 MB/s and its write speeds will max out at 90 MB/s.
