Floppy disks were originally introduced in 1971 and were originally called flexible magnetic disks. They revolutionised computer disk storage for personal computers and became essential in all computers during the 1980s and 1990s to install software, transfer data and create backups. The advent of other portable storage options like memory cards, USB storage devices, CD and DVDs with the ability to store the same amount of data as thousands of floppy disks. This has relegated floppy disks to be used for niche uses mainly in system administration environments.
In answer to the articles question, unless there is a specific requirement for a Floppy Disk Drive, in 2012 and beyond there is no advantage or reason to install a floppy disk drive in your PC. USB storage devices, ever increasing internet speeds and optical media have relegated the humble floppy into ever more niche roles.
