IT之家 6 月 5 日消息，威刚昨日宣布其 Premier Extreme microSDXC SD Express 7.1 存储卡采用了通过任天堂 Switch 2 游戏机兼容性测试的慧荣 SM2708 主控芯片，支持 Switch 2 存储空间扩充。
SD Express 7.1 标准采用 PCIe Gen3 x1 接口与 NVMe 协议，读写速率可达 UHS-II microSD 卡 2.7 倍，这保障了 Switch 2 的非内部存储仍可提供流畅游戏体验。而密钥卡机制的引入也加速了 Switch 2 存储空间的消耗，凸显存储扩展的重要性。
威刚的 Premier Extreme microSDXC SD Express 7.1 存储卡包含 256GB 和 512GB 两个容量版本，顺序读写速度分别至高可达 800MB/s 和 700MB/s，最小写入速度也接近 150MB/s，向下支持 V30 速度等级，享受终身保固。
