Why UHS-II SD Cards Are Essential for 4K Video Recording

Shooting 4K video demands more than just a high-end camera—it requires a high-performance UHS-II SD card for 4K video that delivers reliable write speeds, stable Speed Class performance, and safeguards your valuable content. From YouTubers and wedding videographers to educators and content creators, 4K video recording is now a standard expectation. But most people overlook the one component that makes or breaks the footage: the memory card.If you're using a UHS-I card, you're at risk of dropped frames, overheating, slow file transfers, or worse—data loss.That’s why professionals and serious creators alike rely on UHS-II cards—like Digiera's LSU100 (V60) and LSU200 (V90)—engineered specifically for high-speed, real-time video recording in challenging environments.
