Computer hard disk is the most important storage device of computer. Hard disk (called hard disk in Hong Kong and Taiwan, HardDiskDrive in English, abbreviated as HDD) consists of one or more disks made of aluminum or glass.

The storage medium of the early hard disk was replaceable, but now the typical hard disk is a fixed storage medium, which is sealed inside the hard disk (except for a filter hole to balance the air pressure).
