Promaster SDXC 256GB Performance 2.0

Shot over 4,000 raw files at a wedding and the card never choked once. The write speed is noticeably faster than my older cards, especially when clearing the buffer on burst mode.

Transferred a full day of event photos and clips with zero hiccups, and the write speed kept up even when I was burst-shooting raw files. The 256GB capacity is a sweet spot—plenty of room without needing to swap cards mid-shoot.

Shot 4K video for about 90 minutes straight without any buffer or slowdown, and the U3 speed rating kept up perfectly. The 256GB capacity means I can leave a full day’s work on a single card without swapping.
