About these units
Floppy Disk (5.25", DD) (floppy (5.25" DD))
The 5.25-inch DD floppy stored roughly 360 KB (IBM PC) or 1.2 MB (Apple II and others) depending on format. These flexible disks dominated early personal computing in the 1980s. They were physically fragile but offered an affordable way to distribute software, operating systems, and games. The vast majority of early PC software—from Lotus 1-2-3 to original DOS versions—shipped on 5.25" disks. Their shape and texture became symbols of the early PC revolution, despite their low reliability, susceptibility to dust, and limited capacity.
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.
