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.
Zip 250 (Zip 250)
The Zip 250 increased capacity to 250 MB, improving on the Zip 100 line while retaining backward compatibility. It served as a bridge to larger removable storage formats and remained popular until USB flash drives took over the portable storage market. Designers, schools, and offices used Zip 250 disks for medium-sized multimedia projects, backups, and file transfers. Its existence illustrates the rapid pace of storage innovation—and how even seemingly large capacities were quickly eclipsed.
