Promaster SDXC 256GB Performance 2.0

Shot a two-hour 4K event on it yesterday and never once hit a buffer stall—the write speed held up exactly when I needed it. Transferring the files to my laptop afterward was quick too, which is the part that usually drags. Solid pick for anyone shooting video regularly.

I’ve been using this card for a week now with heavy 4K video recording, and it handles the data stream without any hiccups. The read speed is noticeably faster than my old card when offloading files. Great value for the performance.

Shot over 800 raw images plus 4K video clips at a wedding and this card never once slowed down or stuttered. The write speed kept up with my camera's burst mode without any buffering issues.
