Do I really need a V90 SD card?

Only if your camera records 4K at high bitrates, 4K 120fps, or 8K video. For 4K 30fps at standard bitrates, V30 or V60 is sufficient. For photography only, V30 is fine — burst speed depends more on the camera's buffer than card write speed. V90 is overkill for casual shooting.

Can I use a V90 SD card in any camera?

Yes, V90 cards are backward compatible with any SD card slot. However, you will only get V90 speeds in cameras with UHS-II slots. In a UHS-I slot, the card operates at UHS-I speeds (up to 104 MB/s). Check your camera's specifications for UHS-II support.
