![]() Cassette recorders were available for home computers such as the Apple II and Commodore 64. In the 1980s, computer software was often sold on cassette tape, just like music albums. Magnetic tape isn't that far different from a floppy disk, although it's a lot slower when accessing stored data.

Hard drives soon became the permanent, long-term data storage standard, and next-generation floppy disks would soon take over for portability, both of which we'll get to below. Back then, having two floppy drives made a huge difference because one of them could hold the operating system while the other drive loaded a program, such as Lotus 1-2-3 (Opens in a new window). The drives required a controller card on the motherboard and were connected with ribbon cables. Each floppy diskette could hold 160 kilobytes on one side, or 320KB if you could use both (not all disks were double-sided). The original IBM PC 5150 that debuted in August 1981 offered the option of one or two internal 5.25-inch floppy drives. Soon, Commodore, Tandy, and Atari adopted the same format. Steve Wozniak designed the first external Apple II disk drive in 1978 it used a 5.25-inch floppy disk. The eight-inch size didn't stick around for very long. The round disk inside was in a permanent flexible (floppy) jacket to keep fingers off. Floppy disks originally came in a size of 203.2mm, which is close enough to 8 inches for that to be the moniker used. IBM created the floppy drive as a means of read-only magnetic storage in 1972. ![]() A 5.25-inch floppy drive from an original IBM PC
