Bernoulli Box

The Bernoulli Box (or simply Bernoulli) is a high capacity removable disk storage system that was Iomega Corporation's first popular product (1983). The drive spins a Mylar disk over a read-write head using Bernoulli's principle. The disks are 13.6 cm wide and 14 cm long and have a similar external appearance to 3½-inch floppy disks. Bernoulli disks come in the following capacities: 35 MB, 44 MB, 65 MB, 90 MB (late 1980s), 105 MB, 150 MB, and in 1994, 230 MB. There are three types of drives, grouped by the maximum readable capacity: 90 MB, 150 MB, and 230 MB. None of these drives can write to 44 MB disks.

The disks have a switch to enable and disable write protection.

The original Bernoulli boxes came in capacities of 5, 10, and 20 MB. They were roughly 21 cm by 27.5 cm.

The Bernoulli Box drives were the direct predecessors of Iomega's popular Zip drive, introduced in 1994, which used a similar technology, although smaller and not compatible with Bernoulli disks or drives.
