Adata Premier Extreme 512GB microSDXC SD7.1 Express Card

The Premier Extreme SD7.1 Express memory card delivers next-generation storage performance with transfer speeds up to 800/700MB per second. Built with PCIe Gen3 x1 and NVMe protocols, this 512GB microSDXC card functions like a miniature SSD, providing professional-grade performance for content creators, gamers, and power users.

High-Speed Performance

With read speeds reaching 800MB/s and write speeds up to 700MB/s, the Premier Extreme SD7.1 Express card outperforms traditional storage solutions by significant margins. It's 1.5 times faster than a SATA SSD, 2.7 times faster than high-speed UHS-II SD cards, and 8 times faster than standard UHS-I cards. The PCIe Gen3 x1 bus speed ensures maximum performance whether transferring large files, random small files, or handling dynamic image output.

Nintendo Switch 2 Compatible

The memory card incorporates the Silicon Motion SM2708 SD Express controller, successfully validated through Switch 2 compatibility testing. This ensures optimal performance for game storage, file saving, and high-definition video capture on Nintendo's latest console.

Professional Video Recording

Certified with V30 Video Speed Class support, the Premier Extreme maintains a minimum write speed of nearly 150MB/s, enabling smooth 4K and high-resolution video recording without frame drops or latency issues. Backward compatibility with video speed classes below V30 ensures versatility across different devices.

Universal Compatibility

While optimized for SD Express compatible devices, the card maintains backward compatibility with UHS-I hosts at speeds up to 104MB/s. This ensures functionality across a wide range of cameras, drones, gaming devices, and other equipment.
