Bernoulli Box

The Bernoulli Box was introduced by Iomega in 1982 as the first consumer-friendly removable disk format. The first version offered high-capacity (for the time) disks that held 10MB and were about the size of a sheet of office paper. Over the years Iomega released many versions of the Bernoulli system with smaller physical sizes and higher storage capacities.

Bernoulli drives were essentially a high-capacity floppy disk that were very reliable and widely adopted in the desktop publishing industry of the 1980s. The format was eventually displayed by SyQuest and Zip disks.
