Overview of SanDisk 256GB UHS-I SDXC

Ideal for SD devices designed for Full HD, 3D, and 4K video capture, as well as high-resolution still photography, the SanDisk 256GB Extreme PRO UHS-I SDXC Memory Card offers robust storage with a speed class rating of V30, ensuring a minimum write speed of 30 MB/s. In devices that cannot use the V30 standard, it also complies with U3 standards, maintaining the same minimum write speed. The card supports read speeds up to 200 MB/s and maximum write speeds of 140 MB/s, along with a built-in write-protect switch to prevent accidental data loss.

This memory card can be used in devices that do not support UHS-I/V30/U3 speeds, but note that it will operate at the lower speed class rating of your device, such as UHS-I and U1 (10 MB/s minimum write speed) or Class 10 (also 10 MB/s minimum write speed).

Built to withstand challenging conditions, this card is shockproof and waterproof, functioning efficiently across temperatures ranging from -13°F to 185°F, making it suitable for use in diverse environments, from snowy landscapes to desert heat. Should data integrity be compromised, users can download the RescuePRO Deluxe software and enjoy a limited lifetime warranty.
