Iomega Zip drives were the choice for expanded external storage in the 90’s and early 2000 because alternatives were 1.44MB floppy disks that were becoming a problem due to the nature of files and multimedia need much more space. CD writers were available at the time but were slow and un-reliable at times. Also Zip drives were much cheaper to purchase, however the disks for the Zip drivers were expensive compared to CDRW discs. Storage is 100MB, 250MB & 750MB hence the 3 models that have each number. New models are backwards compatible with smaller size disks. Writing to Iomega’s disk varies depending on which drive interface is used. Drivers below are for the Zip 100, Zip 250, Zip 750 are below for Parallel, USB, SCSI,IDE & PC Card interfaces.
