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.
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.
