Back in the 1990s, a 1.44mb floppy disk was a reasonable storage size for most documents. For bigger documents or backing up an internal hard drive, other options were necessary. You might remember the Zip Drive, but that wasn’t the first large portable media.
The Bernoulli Box was the precursor to the Zip Drive. It used custom media that could store 10s to 100mbs on portable disks. Well, portable compared to carrying around an entire hard drive. Operating using the Bernoulli principal, the drive’s head never comes in contact with the “floppy” material inside the protective case.
Clint of Lazy Game Reviews takes a look at this cool forgotten drive technology in this video.
