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.

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.
