Physical memory (also known as random-access memory (RAM)) is a form of very fast, but volatile data storage. RAM modules are typically measured in nanoseconds (1000− 3), and physical disks are typically measured in milliseconds (1000− 1). This makes physical memory roughly 100,000 times faster than a common physical disk. Therefore, when possible, Windows and Windows Server keep the most frequently accessed pages of memory in physical memory and rely on a disk only if needed.
