Designed for SD devices that can capture Full HD, 3D, and 4K video, as well as raw and burst photography, the 64GB Extreme PRO UHS-I SDXC Memory Card from SanDisk has a capacity of 64GB, is compatible with the UHS-I bus, and features a speed class rating of V30, which guarantees minimum write speeds of 30 MB/s. If your device does not support the V30 standard, this card also supports the U3 standard, which likewise guarantees minimum write speeds of 30 MB/s. Read speeds are supported up to 200 MB/s and write speeds max out at 90 MB/s. A built-in write-protect switch helps to safeguard against the accidental erasure of card data.

While this card has been designed for cameras that are UHS-I / V30 / U3 compatible, it may be used in devices that do not support UHS-I / V30 / U3. However, bear in mind that this card will then default to your device’s speed class and bus rating, such as UHS-I and U1, which supports minimum write speeds of 10 MB/s, or Class 10, which also supports minimum write speeds of 10 MB/s.

As with most SanDisk cards, this memory card is shockproof, X-ray proof, waterproof, while also being able to withstand temperatures from -13 to 185?F, allowing you to take this card with you into extreme environments, such as snow, deserts, and pools.
