About these units
Floppy Disk (3.5", HD) (floppy (3.5" HD))
The 3.5-inch High Density (HD) floppy stored 1.44 MB, becoming one of the most iconic storage formats of the 1990s. HD floppies were ubiquitous—used for school assignments, office documents, driver disks, BIOS updates, and even early game installations. Their capacity was sufficient for word processing files, spreadsheets, and modest multimedia content of the era. Although minuscule by modern standards, the HD floppy revolutionized everyday computing by offering a cheap, standardized, nearly universal storage medium. Its influence persisted until USB drives and CDs supplanted it in the early 2000s.
Floppy Disk (3.5", DD) (floppy (3.5" DD))
The 3.5-inch Double Density (DD) floppy disk typically held 720 KB of data and represented the evolution from earlier, more fragile 5.25-inch formats. Encased in a rigid plastic shell, 3.5" floppies provided improved durability, portability, and reliability. DD floppies became widely used in the late 1980s, particularly on early Macintosh and IBM-compatible computers. They were ideal for document storage, small software programs, and system utilities. Their limited capacity symbolized the constraints of early personal computing, forcing developers to design highly compact code and carefully manage file size. Despite their modest storage, DD floppies played a crucial role in early software distribution and data portability.
