The Iomega Bernoulli Box was an external data storage device using a Bernoulli principle-based aerodynamic cushion of air to float flexible magnetic disk cartridges near its read/write heads, offering high-capacity, "crash-proof" data storage for microcomputers in the 1980s and early 1990s. It allowed for removable storage, virtually unlimited capacity by adding more cartridges, and was faster than tape drives while being nearly damage-free if the disk deformed or a particle was encountered.

Key Features and Functionality

Bernoulli Principle: The drive uses the scientific principle discovered by Daniel Bernoulli, where a fast-moving fluid creates a low-pressure area. In the Bernoulli Box, a spinning flexible disk floats on this "cushion of air" created between the disk and the drive head.

Crash-Proof Design: Unlike hard drives with rigid platters, the Bernoulli Box's design was essentially crash-proof. If the disk encountered dust or a physical shock, the disk would simply move away from the head instead of the head colliding with the disk, which would damage a traditional hard drive.

Removable Media: The system used large, flexible disk cartridges that could be inserted and locked into the drive.

High Capacity and Speed: The Bernoulli Box offered a high-capacity alternative to floppy disks and was significantly faster than tape drives, making it a popular choice for high-speed removable storage.

External and Portability: It was an external device connected to a computer, allowing for easy transport of large files and secure offline storage.
