About these units
Floppy Disk (5.25", HD) (floppy (5.25" HD))
The 5.25-inch HD floppy stored 1.2 MB and represented the final evolution of the large-format floppy. HD versions were common in late-1980s IBM business systems and were used to distribute larger software packages and operating systems. However, the rise of the more compact and durable 3.5" floppy soon overshadowed the HD 5.25" format. Their rapid decline highlights how the industry moved toward miniaturization and higher reliability in portable storage.
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.
