    What is a RAM disk?

    • A RAM disk is a portion of RAM which is being used as if it were a disk drive. RAM disks have fixed sizes, and act like regular disk partitions. Access time is much faster for a RAM disk than for a real, physical disk. However, any data stored on a RAM disk is lost when the system is shut down or powered off. RAM disks can be a great place to store temporary data.

    For short, a RAM disk is a virtual file system that runs entirely from your PC’s main memory, which means it’s lightning fast to read and write anything you want.
