Iomega released the 1GB JAZ Hard Disk removable cartridge drive system in 1995, and releasing an updated 2GB version in 1998 (which is fully backward compatible with 1GB cartridges). Iomega made the JAZ in both internal (SCSI & IDE in 3.5″ form factor) and external (SCSI & Parallel) configurations.
I use these for mass storage, backup, and data transfer on most of my vintage SCSI equipped computers like vintage Apple II and Macintosh computers, and even a few of my SCSI equipped vintage PCs. These drives are typically quite inexpensive on the 2nd hand market, I have 2x 2GB and 3x 1GB drives and a large stack of cartridges in both 1GB and 2GB capacities.
Being a removable hard disk platter based system, the drives and disks, when inserted should be handled gently as you would any hard disk, however when handled with care I have found these to be much more reliable than Iomega’s ZIP drive offering.
