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 (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.
