Extreme PRO 256GB SDXC Card 170MB/s 633x V30 Card
The 256GB Extreme PRO UHS-I SDXC Memory Card from SanDisk is designed for use with your SD-compatible devices that can capture Full HD, 3D, and 4K video, as well as RAW and burst photography. Compatible with the UHS-I bus, it 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 also guarantees minimum write speeds of 30 MB/s. Read speeds are supported up to 170 MB/s and write speeds up to 90 MB/s. It may be used in devices that do not support UHS-I / V30 / U3. However, the 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.
SanDisk cards are water, shock, x-ray, and temperature proof to help protect your data. A built-in write protect switch also provides an additional safeguard for your content, and this memory card includes downloadable RescuePRO data recovery software, which is good for one year of use and helps you restore accidentally deleted images.
