SanDisk Extreme PRO 64 GB SDXC I U3 10 60MB/s

Designed for SD devices that can capture video, as well as raw and burst photos, SanDisk’s 64GB SDXC Extreme memory card is 64GB capacity, UHS-I bus compatible, and rated at V30 speed class, which guarantees minimum write speeds of 30 MB / s. If your device doesn’t support the V30 standard, this card also supports the U3 standard, which also guarantees minimum write speeds of 30MB / s. Read speeds are supported up to 60MB / s.

A built-in write protection switch helps protect against accidental erasure of card data. Although this card has been designed for cameras compatible with UHS-I / V30 / U3, it can be used in devices that are not compatible with UHS-I / V30 / U3. Please note, however, that this card will have your device’s default speed class and bus rating, such as UHS-I and U1, which supports minimum write speeds of 10MB / s, or Class 10, which also supports minimum write speeds of 10 MB / s.
