U盘这钟闪存式移动硬盘成长已经有很多年了，它的容量也从初期的以MB为单元，成长到此刻以GB为单元，甚至也有以TB为单元的。除了容量变大，U盘的写入速度也变快了很多。这里我们就讲讲甚么是高速U盘。
我们知道，U盘走过了USB 1.0、USB 2.0、USB 3.0这几个标准的阶段，USB 1.0的U盘广泛被裁减了。先从USB 2.0标准来讲，USB 2.0接口标准的三种速度规格为：
High-speed 25Mbps～40Mbps(最大48Mbps) (高速)
Full-speed 500Kbps～10Mbps(最大12Mbps) (全速)
Low-speed 10Kbps～100Kbps(最大1.5Mbps)(低速)
因而可知，USB 2.0的高速U盘最大速度为48Mbps，这在我们泛泛操作中还算可以接受。但这只是理论速度，现实操作时不大可能达到这样的传输速度。而且，随着传输系统镜像、高清影音文件等需求的增长，USB 2.0标准的速度慢慢显得落后，采用USB 3.0标准的高速U盘也已经推出。
遵守公然的材料显示，USB3.0的最大传输带宽高达5.0Gbps(即140MB/s)，这是USB 2.0标准传输速度的10倍以上。当然，这也是理论速度，但现实速度也要比USB 2.0快很多。所以，此刻的高速U盘，就必须是采用USB 3.0标准的U盘。以下是USB3.0是速度：
USB3.0速度为：读速度为60MB/s~140MB/s，写速度为50MB/s~90MB/s
以上就是对甚么是高速U盘的解读了。速度越快越好，速度快读取、复制文件的时候所用时间越短，这些常识对于经常接触数码设备的用户来讲，或许算得上了如指掌。但信任对大都科技小白用户来讲，还是有很大的科普浸染的，最少买U盘时也能有更了然的选择。
