A hard disk drive is a digitally encoded non-volatile storage device which stores data on the magnetic surfaces of hard disk platters. Hard disks were originally developed for use in connection with a single computer. Later, as a way of guarding against hard disk failure, they were arranged into configurations such as redundant array of independent disks (RAID). Hard disks are also used in network attached storage (NAS) devices or in a storage area network (SAN). Over time, applications for hard disk drives have expanded beyond computers to include video recorders, audio players, digital organizers, digital cameras ...
