Jaz Drive
     
         {Iomega Corporation}'s drive which takes
        removable one or two {gigabyte} disk cartridges which contain
        conventional {hard disks}.
     
        Internal and external drives are available claiming an average
        transfer rate of 330 {megabytes} per minute - though that is
        dependant on the {SCSI} adapter, the parallel port adapter is
        unlikely to reach anything like this speed.  The Jaz drive was
        the successor to the company's more establistablished {Zip
        Drive}.
