The Bernoulli Box is a high capacity removable disk storage system that was Iomega Corporation's first popular product (1983). It spins a MylarŽ disk over a read-write head using Bernoulli's principle. The disks appear similar to 3˝ floppy disks, and are 13.6 cm wide and 14 cm long. They come in several 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.
