A RAM disk or RAM drive is a block of RAM (primary storage or volatile memory) that a computer's software is treating as if the memory were a disk drive (secondary storage).

Because the storage is in RAM, it is volatile memory, which means it will be lost in the event of power loss, whether intentional (computer reboot or shutdown) or accidental (power failure). This is sometimes desirable: for example, when working with a decrypted copy of an encrypted file, or for storing a web cache (doing this on a RAM disk can also improve the speed of loading pages).
