A hard disk drive (sometimes abbreviated as Hard drive,
HD , or HDD ) is a non-volatile memory hardware device that
permanently stores and retrieves information. There are
many variations, but their sizes are generally 3.5" and 2.5"
for desktop and laptop computers respectively. A hard drive
consists of one or more platters to which data is written
using a magnetic head, all inside of an air-sealed casing.
Internal hard disks reside in a drive bay, connect to the
motherboard using an ATA, SCSI , or SATA cable, and are
powered by a connection to the PSU (power supply unit).

A hard drive can be used to store just about any type of
data, including pictures, music, videos, and text documents.
Computers have a hard drive and use it to store files for the
operating system and software that run on the computer, as
well as files created or downloaded to the computer by a
user.
