The SanDisk 256GB Extreme PRO UHS-I SDXC Memory Card is designed for SD devices that can capture Full HD, 3D, and 4K video, as well as raw and burst photography. This memory card has a capacity of 256GB, is compatible with the UHS-I bus, and features a speed class rating of V30. Its speed class rating guarantees minimum write speeds of 30 MB/s. This card also supports the U3 standard, which also guarantees minimum write speeds of 30 MB/s. With read speeds up to 170 MB/s and write speeds up to 90 MB/s, this memory card has a built-in write-protect switch, which helps safeguard against the accidental erasure of card data. Though this card is designed for cameras that are UHS-I / V30 / U3 compatible, it may be used in devices that do not support UHS-I / V30 / U3. If used with a device that does not support UHS-I / V30 / U3, the card will default to your device's speed class and bus rating. As with most SanDisk cards, this memory card is X-ray proof, shockproof, waterproof, and is able to withstand temperatures from -13 to 185°F, allowing you to take this card with you into extreme environments, such as deserts, snow, and pools. In the event that the card's data becomes compromised, you have the option to download RescuePRO Deluxe software as well as a limited lifetime warranty.
