External Serial ATA Cable (ESATA)外部用SATA 线缆Product Introduce(产品介绍):ESATA is external SATA II style, i.e. the extension of the industry connection Serial ATA (SATA).ESATA is a kind of extended SATA port, to use for connection of outer instrument instead of internal instrument. In short, by ESATA technology, it makes external I/O ports use SATA2 function.The design of SATA port is only for internal system of computer. Now end user can insert SATA hard disk outside of computer by ESATA technology, but the HD can only be inserted inside computer before.ESATA has the most advantage in transmission speed, it can provide 3000Mb/s transmission speed at most,which exceed USB2.0 and IEEE1394, and it can keep the convenience in hot insertion in /out function, so it is very convenient for end user, no need shut down the computer and end user can connect or remove SATA device.ESATA 就是外置式SATA II 规范，是业界标准接口Serial ATA(SATA)的延伸。ESATA 是一种扩展SATA接口，是用来连接外部而不是内部SATA 设备。简单的说就是通过ESATA 技术，让外部I/O 接口使用SATA2功能。SATA 接口的设计仅供做为使用于系统机箱内。ESATA 的出现将使得用户可以在电脑外部连接SATA硬盘而不像过去只能局限于电脑内部。ESATA 的拥有极大的传输速度优势：最高却可提供3000Mb/s 的数据传输速度，远远高于USB2.0 和IEEE1394，并且依然保持方便的热插拔功能，用户是不需要关机便能随时接上或移除SATA 装置，十分方便。
