256GB SDXC card for 4K UHD video

The SanDisk Extreme SDXC card provides 256GB of storage for cameras that use the UHS-I interface. It carries U3, Class 10 and V30 ratings, making it suitable for 4K UHD video and sequential burst photography. Photographers and videographers who need reliable capacity for high-resolution files will find it fits the workflow.

UHS-I bus limits sustained write to 70MB/s

The card operates on the UHS-I bus, which caps maximum transfer rates at the 150MB/s read and 70MB/s write figures quoted. Continuous 4K recording relies on the V30 guarantee of 30MB/s minimum write speed. Buyers who need faster sustained throughput for higher bitrate formats or simultaneous multi-stream capture will find the UHS-I interface a bottleneck.

Simple insertion, watch for device compatibility

Installation is a matter of sliding the card into the camera or reader slot until it clicks. The most common issue is using the card in a device that only supports the older SDHC standard, which cannot address 256GB capacities. Users should also verify that their host device supports UHS-I to obtain the rated speeds.

Questions about this item

Should I pick the 256GB Extreme or a smaller capacity in the same line?

The 256GB version qualifies for the 70MB/s shot-speed rating and 150MB/s transfer rating that apply from 128GB up, so it is the smallest capacity that delivers the full Extreme performance tier.

What does the 150MB/s figure mean when the card is inside my camera?

That is the maximum transfer speed for offloading files to a computer; in-camera write performance tops out at 70MB/s, which is the speed that governs burst shooting and 4K video recording.

How does the UHS-I interface affect real-world speed?

The card uses the UHS-I bus and carries U3 and V30 ratings, guaranteeing a minimum sustained write of 30MB/s for uninterrupted 4K UHD capture.
