U盘的称呼最早来源于朗科公司生产的一种新型存储设备，名曰“优盘”，也叫“移动硬盘”使用USB接口进行连接。
USB接口就连到电脑的主机后，U盘的资料就可放到电脑上了。
电脑上的数据也可以放到U盘上，很方便。
而之后生产的类似技术的设备由于朗科已进行专利注册，而不能再称之为“优盘”，而改称谐音的“U盘”或形象的称之为“闪存”“闪盘”等。
后来U盘这个称呼因其简单易记而广为人知，而直到现在这两者也已经通用，并对它们不再作区分。
其最大的特点就是：小巧便于携带、存储容量大、价格便宜。
是移动存储设备之一。
一般的U盘容量有1G、2G、4G、8G、16G等，价格上以最常见的2G为例，55元左右就能买到。
U盘容量有了很大程度的提高，如：4G、8G,16G的U盘。
它携带方便，属移动存储设备，所以当然不是插在机箱里了，我们可以把它挂在胸前、吊在钥匙串上、甚至放进钱包里。
[编辑本段]存储原理计算机把二进制数字信号转为复合二进制数字信号（加入分配、核对、堆栈等指令）读写到USB芯片适配接口，通过芯片处理信号分配给EPROM2存储芯片的相应地址存储二进制数据，实现数据的存储。
E PROM2数据存储器，其控制原理是电压控制栅晶体管的电压高低值，栅晶体管的结电容可长时间保存电压值，也就是为什么USB断电后能保存数据的原因。
