Floppy disk
A floppy disk is a data storage device that is composed of a circular piece of thin, flexible (i.e. “floppy”) magnetic storage medium encased in a square or rectangular plastic wallet. Floppy disks are read and written by a floppy disk drive or FDD. Unlike most hard disks, floppy disks (often called floppies or diskettes) are portable, because you can remove them from a disk drive. Floppy disks are slower to access than hard disks and have less storage capacity. The 3.5″ floppy can hold on 1.4Mb of data, compared to 700Mb on a CD, 4.3Gb on a DVD, and 7.8Gb on a DVD Dual Layer. Floppies are a legacy media, and are rarely found in use.
