There are different types of disk drives for different types of disks. For example, a hard disk drive (HDD) reads and writes hard disks, and a floppy drive (FDD) accesses floppy disks. A magnetic disk drive reads magnetic disks, and an optical drive reads optical disks.

Disk drives can be either internal (housed within the computer) or external (housed in a separate box that connects to the computer).
