SanDisk 256GB Extreme SDXC Memory Card

The SanDisk Extreme SD UHS-I memory card is engineered to save time during media transfers, boasting read speeds of up to 180MB/s powered by SanDisk QuickFlow Technology. This card can be paired with the SanDisk Professional PRO-READER SD and microSD to achieve maximum speeds (sold separately). With shot speeds of up to 130MB/s and UHS speed Class 3 (U3) recording, users can capture high-resolution, stutter-free 4K UHD video.

The card's read speed of up to 180MB/s is achieved through proprietary technology that goes beyond the standard UHS-I 104MB/s, but requires compatible devices capable of reaching such speeds. Based on internal testing, actual performance may vary depending on the host device, interface, usage conditions, and other factors. 1MB equals 1,000,000 bytes.

SanDisk QuickFlow Technology is exclusive to the 64GB, 128GB, 256GB, and 512GB capacities of this memory card. 1GB equals 1,000,000,000 bytes, and actual user storage will be less than the total listed capacity.

The UHS Speed Class 3 (U3) and Video Speed Class 30 (V30) designations indicate the card's performance capabilities for 4K UHD video recording with enabled UHS host devices. The V30 rating specifically denotes a sustained video capture rate of 30MB/s.

Full HD (1920x1080) and 4K UHD (3840 x 2160) video support may vary based on the host device, file attributes, and other factors. Users can refer to the HD page on the SanDisk website for more information.

In summary, the SanDisk Extreme SD UHS-I memory card offers exceptional transfer speeds, making it a suitable choice for capturing high-quality 4K UHD video and sequential burst mode photography, while providing reliable performance and compatibility with a range of host devices.
