Hard drive

What is a computer hard drive?

A computer hard drive can be used to store large amounts of data, like photos, music, files and videos, as well as the computers operating system. A hard drive may also be referred to as a 'hard disk drive' (HDD) or (HD) for short. A computer must have at least one form of hard drive to function but can have multiple hard drives if additional storage is required. Additional drives are often external to the computer, but a large computer may have multiple internal drives. See 'SSD' for alternative hard drive replacement
