Designed and tested to UHS-II U3 Class 10 specifications, Premier ONE SDXC cards reach 290MB/s read and 260MB/s write. Their microSDXC series counterparts perform at 275MB/s read and 155MB/s write. Both microSD and SD versions support V90 video speeds, or 90MB/s of raw video recording, which is more than sufficient bandwidth for capturing 4K, 8K, and VR content. Action camera and 360-degree live capture applications also stand to gain much from access to such high data rates, which enable uncompressed recording, no lag, no buffering, and no reduction in resolution.

MLC Flash, robust build, data integrity, and ample capacity

All Premier ONE UHS-II U3 cards use high grade 3D MLC Flash for long-lasting optimal performance. They support automatic error correction to increase data integrity, and pass strenuous water, dust, shock, and X-ray proof testing. The cards are thus very suitable for outdoors activities, live recording and reporting, and international professionals that travel long distances and experience diverse environments. Consumers can choose from 64GB, 128GB, and 256GB models as needed for instant storage expansion on iOS, Windows, Mac OS, and Android in virtually every class of device thanks to the universality of the microSD/SD format.

Perfect for Full HD content

Premier microSDXC/SDHC models pack 16GB, 32GB, 64GB, and 128GB on UHS-I Class 10 cards capable of 85MB/s read and 25MB/s write. That makes them very suitable for users requiring consistent-quality Full HD 1080p recording, playback, and sharing. In addition to practically universal compatibility, the cards are rugged, passing strict water, dust, shock, and X-ray proof testing. Ensuring customers get a complete package on any budget, ADATA integrates automatic error correction on Premier UHS-I cards.
