<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">MicroSDXCI指的是这张卡的类型，Micro<span style="color: black;">便是</span>指的这张卡为TF卡（MicroSD卡），<span style="color: black;">无</span>Micro字样则为标准的SD卡。SDXC<span style="color: black;">显示</span>该卡的容量在64GB以上，<span style="color: black;">倘若</span>卡面上是SDHC则这张卡容量在32GB以下。而SDXC后面的罗马数字I全写为UHS-I，<span style="color: black;">表率</span>总线接口速度，UHS-I的速度为104MB/s。</p><img src="https://p3-sign.toutiaoimg.com/tos-cn-i-tjoges91tu/TT99MS79AVZZKh~noop.image?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1728814185&x-signature=s38IJEKh4MaxKSrmuShndWkIroQ%3D" style="width: 50%; margin-bottom: 20px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">U3、V30、A2指的是这张存储卡的速度等级，较早的<span style="color: black;">制品</span>还<span style="color: black;">能够</span>见到C10的标识。从下图的内容可知，U、V以及C的数值越高，这张卡的<span style="color: black;">连续</span>写入<span style="color: black;">亦</span>更快。例如U3的<span style="color: black;">连续</span>写入速度最低为30MB/s，而U1<span style="color: black;">连续</span>写入速度最低为10MB/s，与C10一致，<span style="color: black;">因此呢</span><span style="color: black;">此刻</span><span style="color: black;">非常多</span>U1规格的存储卡都去掉了C10的标识；而V则<span style="color: black;">表率</span>着视频速度等级，例如V30对应着30MB/s的最低写入速度，<span style="color: black;">能够</span>支持4K 30FPS视频的拍摄，V60则<span style="color: black;">能够</span>支持4K 120FPS视频的拍摄等。</p><img src="https://p3-sign.toutiaoimg.com/tos-cn-i-tjoges91tu/TT99MSeECdAxsz~noop.image?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1728814185&x-signature=hIKRGCtNIV8ccL30zVw89twqHw4%3D" style="width: 50%; margin-bottom: 20px;">
