Promaster SDXC 256GB Velocity CINE

I've been editing 4K footage straight off this card without any stuttering—the V90 speed rating makes a noticeable difference. It's a solid upgrade for anyone using a UHS-II camera.

Switching to a UHS-II reader finally let me take full advantage of this card's 250MB/s write speed, which cuts my file transfer times in half. The V90 rating gives me peace of mind shooting high-bitrate 4K without worrying about buffer drops.

Editing 4K footage straight off this card in my UHS-II reader feels almost instant, and the 250MB/s write speed has yet to hiccup on a single burst of shots. I’ve filled it to the brim twice now and it keeps a steady pace even when I’m hammering it with long video clips.
