About these units
Floppy Disk (3.5", ED) (floppy (3.5" ED))
The 3.5-inch Extended Density (ED) floppy disk increased storage to 2.88 MB, nearly double the HD version. Despite the additional capacity, ED disks never achieved widespread use. They required compatible drives, were more expensive, and emerged during a period when optical and magnetic storage technologies were advancing rapidly. Their brief existence reflects an inflection point in storage history—where incremental magnetic improvements could no longer keep pace with the exponential growth in software size and consumer demand.
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.
