Techopedia Explains Disk Drive

A disk drive is one of the most important computer components that helps users store and retrieve data from a disk. The nature and type of disk drive vary on par with the underlying disk.

For example, a hard disk, which is known as a hard disk drive (HDD), is generally embedded within the disk itself. For floppy disks, an external component is installed within a computer and performs read/write (R/W) operations when a floppy disk is inserted.
