RAM is the term used to describe the memory system of computers. The amount of RAM, or random access memory, that computers contain varies widely among operating systems. All computers come with a standard amount of integrated memory, and their storage capacities can be increased with the installation of certain devices, called RAM disks or RAM drives.

RAM disks or drives are external devices that can be installed on many types of computer systems. RAM disks essentially enhance the storage capacity of systems, which improves their memories and may even boost performance and operation speed. RAM disks are virtual hard drives that are inserted into the RAM of computers. RAM disks can be created and installed on home computer systems, provided computers have a sufficient amount of memory. While RAM disks improve the operating efficiency of computers, they also require a substantial amount of memory to be produced in the first place.

Once installed, however, RAM drives can multiply the storage capacities of computers and serve as data storage devices to save duplicate copies of important documents. RAM drives can be used to store files, folders and documents, as well as run entire programs. RAM drives come in various sizes, which determines which computer systems they are best suited for.
