Jaz drive

The Jaz drive was a series of removable hard disk drives from Iomega.

Description
Though Jaz drives were designed to externally resemble their predecessor, the Zip drive, they were based on different storage technology which relied on cartridges containing hard disk platters, instead of floppy disk-like material. Internal and external drives were available, claiming an average transfer rate of 330 megabytes per minute through a SCSI interface.

History
The first drives, which supported 1 gigabyte cartridges, were introduced in December 1995. A 2 gigabyte version was introduced in February 1998. These never achieved the success of Zip disks as computers of the time began adopting rewritable optical drives instead. Like Zip drives, they were also prone to reliability problems.
