Is this card fast enough for 4K video?

Yes. Its V30 and U3 ratings guarantee a sustained write speed suitable for 4K video in cameras that record to SD.

Will it work in my camera?

It fits any device with an SDXC slot. Cameras limited to UHS-I get the full benefit; UHS-II cameras will run it at UHS-I speeds.

UHS-II cards read and write faster in cameras that support that bus. This card is cheaper per gigabyte and fine for UHS-I bodies.

To reach the 170MB/s read speed you need a UHS-I reader that supports the faster bus. A basic reader will work but slower.

It suits long shoots and video, but some photographers prefer splitting footage across two smaller cards so one failure costs less.

SanDisk rates it resistant to water, temperature extremes, shock and X-rays, which covers most outdoor shooting conditions.
