A medium-capacity removable disk storage system, introduced by Iomega in late 1994. Originally it had a capacity of 100 MB, but later versions increased this to first 250 MB and then 750 MB.
The format became the most popular of the super-floppy type products but never reached the status of a quasi-standard to replace the 3.5-inch floppy disk.
It has been superseded by flash drive systems as well as rewritable CDs and DVDs, and is fading in popularity.
The Zip brand was also used for internal and external CD writers known as Zip-650 or Zip-CD.
