Iomega’s Bernoulli disc was first introduced in 1982 in it’s 8-inch format, and was Iomega’s first widely known product (this was 13 years before they launched the Zip drive). The drive was known as the ‘Bernoulli Box’ and was a high-capacit
At a time when 5.25-inch floppy discs held a maximum of 1.2 MB when used in the IBM PC AT of 1983, the Bernoulli Box’s choice of 5, 10 or 20 MB capacity seemed enormous, especially since contemporary hard drives still only held up to 30 MB. A review
The Bernoulli Box system used large 11 by 8-inch rigid cartridges containing an 8-inch flexible disk which span at 1,500 rpm. It was somewhat more reliable than a contemporary hard disk drives, since a head crash was impossible; a power cut or knock to
Due to the size of the drives, these were external devices, connected to an IBM PC via a controller card or to an Apple Macintosh via the communications ports.
Disks were inserted into the drive, and a latch turned to lock it in place. The disk could not be removed from the drive until it span down and the latch can then be released. Drives required cleaning, and a cleaning cartridges was available, and the h
The Bernoulli Box was expensive, and in 1987 cost more than many PC clones. The cartridges alone cost $79 in 1985, but at the time there were no other options for the amount of removable storage offered by a Bernoulli Box, unless you were happy to use
It was replaced by the Bernoulli Box II that used 5.25-inch form factor disks and eventually offered larger capacities of up to 230 MB.
