RAM Disk

A simulated disk drive created by allocating a portion of RAM in a computer system. A RAM disk will generally behave just like a regular hard disk drive, only it is usually much, much faster, which makes them handy for operations where the drive needs to be accessed a lot. There are software programs for most computing platforms that allow the user to configure RAM disks. Unlike a hard drive, however, a RAM disk is not a place for permanent storage. When the power is removed the contents of the RAM disk will be lost.
