The speed at which systems and applications run on a computer is affected by the hardware configuration, and one of the computer components that plays a decisive role in this issue is the hard disk drive. In addition to traditional HDDs and now common SSDs, there is a virtual disk called RAM disk. It is created from a part of the physical memory installed on the computer, and it has the advantage of being much faster (hundreds to thousands of times faster) than mechanical hard disks and even SSDs for reading and writing data.
