The Jaz drive[1][2] is a removable hard disk storage system sold by the Iomega company from 1995 to 2002.
Following the success of the Iomega Zip drive, which in its original version stores data on high-capacity floppy disks with 100 MB nominal capacity, and later 250 and then 750 MB, the company developed and released the Jaz drive. First shipping to OEMs in December 1995, the Jaz drive featured 1 GB capacity per removable disk.[3] A new Jaz drive model, released in February 1998, increased the individual disk capacity to 2 GB.[4]
The Jaz drive uses a SCSI interface,[5] with both internal and external drive models. Iomega produced a Jaz Jet SCSI adapter PCI card for PCs. Iomega also produced a number of external adapters, including the Jaz Traveller interface that connected it to a standard parallel port, and, later, a SCSI-USB adapter and SCSI-Firewire adapter. An ATA version of the drive was planned but never released.
So the focus now is on selling Zip and its sister data-storage products, Ditto and Jaz
