Bernoulli drive
The Bernoulli drive is a computer disk drive first developed by Iomega in 1983. A Bernoulli drive is just like a floppy diskette however the internal disk disk is much more rugged and capable of running faster and holding more, however, still not as fast as a hard disk drive. Bernoulli disks were commonly available in 5, 10, and 20MB size and was even available up to 230MB. This drive was later replaced by the Iomega Jaz drive and Zip drive.
