Iomega released the Bernoulli Box II in 1987, replacing the original Bernoulli Box with its 8-inch disks with a smaller version using 5.25-inch form factor disks. Initially offering the same capacity of 20 MB as the original, this was increased over time, and eventually offered 230 MB by the time it was replaced by the Zip disk.
Unlike the original Bernoulli Box, the Bernoulli Box II was available as an internal unit, although it was still available as an external unit with one or two drives in a self-contained case connected via an external SCSI interface.
Dimensions: 137.7 mm x 135.9 mm x 9.3 mm
Capacity: 20 MB to 230 MB
