Do I need a UHS-II camera to use this card?

The card works in any SD slot, but you only get its UHS-II read and write speeds in a UHS-II capable camera or reader. In a UHS-I device it falls back to slower UHS-I speeds.

Is it fast enough for 8K video?

Yes. Its V90 rating guarantees a sustained minimum write speed of 90MB/s, which covers 8K recording on cameras that specify V90 media.

How many photos or how much video fits on 256GB?

Capacity depends on your camera and settings. SanDisk's own figures for its 2TB version show over 1,100 minutes of 8K at 30fps and more than 47,000 24MP RAW stills, so 256GB holds roughly an eighth of that.

Is it waterproof and shockproof?

It is IP68 rated for water and dust and tested to survive drops up to 6 meters, so it handles rain, dust and knocks in the field.

Does it work in a DSLR?

Yes, it fits DSLR and mirrorless cameras with SD slots. Older DSLRs with UHS-I slots will run it at UHS-I speeds.

What comes in the box?

The card itself. A UHS-II reader is sold separately and is needed to reach the full read speed.

Our take on the SanDisk 256GB Extreme PRO SD UHS-II V90 Card

The SanDisk Extreme PRO SD UHS-II V90 is a professional SDXC card built for high-bitrate video and fast burst shooting. It guarantees a sustained minimum write speed of 90MB/s, which meets the V90 rating that 8K and high-frame-rate 4K recording demand, and reads at up to 310MB/s for quick offloads. It is IP68 rated for water and dust and survives drops up to 6 meters, so it holds up in rough field work. It suits mirrorless and DSLR shooters who need reliable sustained writes more than the fastest possible read speeds; rivals like Lexar and ProGrade V90 cards compete closely, but this one is widely trusted for consistent performance.
