The fact that you can store massive ammounts of information in a device about the size of a quarter is hard to believe. And the fact that it’s compatible with devices that run the gamut—from smartphones and tablets to cameras and the Nintendo Switch—is even crazier. These memory cards from Adata meet the latest UHS-II standards, providing read speeds up to 290MB per second—which is nearly three times faster than UHS-I. They also offer V90 video speed for uninterrupted recording of Ultra HD 8K, 4K, and 3D/VR video on any device that supports it. To ensure they’ll hold up over time, each card passes rigorous waterproof, shockproof, X-ray proof, and anti-static testing—and they’re backed by automatic error correcting code (ECC) and a lifetime warranty.
