Unverified读取UHS-II SD卡需读卡器同时支持UHS-II（触点为两排），否则会降速到UHS-I的104MB/s上限；老读卡器只有一排触点无法发挥高速卡性能91% similarUnverified买存储卡要认准UHS-I与UHS-II接口区别：UHS-II卡背面有第二排金手指，理论速度可达312MB/s，但只有支持UHS-II的设备才能发挥，UHS-I设备插上会降速86% similarUnverified读卡器优先选UHS-II规格(理论312MB/s)搭配对应SD卡才能发挥高速，若相机卡为UHS-I或手机接口USB2.0，买UHS-II读卡器是浪费，速度反被最短板限制85% similarUnverified只使用UHS-I的SD卡（读取上限约104MB/s）不必购买UHS-II读卡器，UHS-II读卡器读UHS-I卡不会提速；但UHS-II读卡器向下兼容UHS-I卡可作为未来升级预留82% similarUnverifiedUHS-II卡有两排金手指针脚，UHS-I只有一排；UHS-II卡向下兼容UHS-I插槽但速度降级，需设备也支持UHS-II才能发挥全速79% similar
