The card has the speed, capacity and performance needed to record cinema-quality 4K video (4096x2160p). The difference is mainly in the support for higher transfer rates, which makes this card extremely suitable for use with high-quality camera models. Various effects like data retention, read disturb limits, or temperature can impact data reliability. I was disappointed though that, after formatting in the camera, the capacity of the card was only 111GB. In addition, the world’s first 512GB large capacity card offers non-stop recording for your masterpiece.
