What does the V90 rating mean?

V90 guarantees a sustained minimum write speed of 90MB/s, which is enough for 8K and high-bitrate 4K recording in compatible cameras.

Will it work in my camera?

It works in any SDXC-compatible camera, but you only get UHS-II speeds in cameras with a UHS-II slot. UHS-I cameras run it at their own slower limit.

To reach the rated read and write speeds you need a UHS-II card reader. A standard UHS-I reader will transfer more slowly.

It holds a substantial amount of 8K and 4K footage, but high-bitrate 8K fills space quickly, so many shooters pair it with a second card.

It is much faster in UHS-II cameras, clearing buffers and offloading files quicker, but it costs more and offers no benefit in UHS-I-only bodies.

Yes. The fast write speed clears camera buffers quickly during continuous RAW shooting, which suits sports and wildlife work.
