        RAM drive uses part of your computer's   random -access memory (RAM) to simulate a hard disk drive.This device driver must be load by a ＜DEVICE＞ or ＜DEVICEHIGH＞ command in your CONFIG.SYS file.
        RAM drives are faster than hard disk drives because computer can read information faster from memory than from a hard disk. A RAM drive appears to be a normal hard disk drive； you can use it as you could any hard disk drive.The most important difference between a real
        disk drive and a RAM drive is that because it exists only in memory，information on a RAM drive is lost when you turn off or restart computer. You can set up as many RAM drives as you want，up to the amount of your computer has. To do this， add one RAMDRIVE.SYS line to your
        CONFIG.SYS file for each additional RAM drive you want.
        虚拟盘
        虚拟盘使用计算机的随机存储器(RAM)的部分来模拟一个硬盘驱动器。该设备驱动程序必须在你的CONFIG.SYS文件中用DEVICE或DEVICEHIGH命令来加载。
        由于计算机从内存读取信息比从硬盘要快，所以虚拟盘比硬盘快得多。虚拟盘可视作普通硬盘；你可以象使用任何硬盘一样使用虚拟盘。真正的磁盘和虚拟盘两者之间最重要的不同是虚拟盘仅存在于内存，当你关机或重新启动计算机时，虚拟盘上的信息被丢失。你想要多少个虚拟盘就可以建多少个，最多到你的计算机所有的内存总数。为此，只需为你附加的每一个虚拟盘在CONFIG.SYS文件中增加一行RAMDRIVE.SYS。
