是基于WDF写的一个实现虚拟磁盘驱动，用部分内存虚拟出一个硬盘（实际不存在的银盘）。

Ramdisk又叫虚拟磁盘或者内存盘，由于内存具有很高的速度，远远高于新出的SSD及传统主流的机械硬盘，于是便有人提出了用内存来替代硬盘的方法，这便是ramdisk。-Is based on the WDF to write a virtual disk drive, some memory with a virtual hard disk (the actual silver does not exist). Ramdisk memory is called virtual disks or disk, because the memory has a very high speed, much higher than the new out of the mainstream SSD and traditional mechanical hard disk, so it was suggested to replace the hard drive with the memory method, which is the ramdisk.
