The Iomega ZIP 750 is an external USB Zip drive designed for compact, portable backup and file transfer using Zip disks (750 MB capacity). It’s a niche option best for people trying to access existing Zip archives or maintaining legacy workflows, with mixed buyer sentiment mainly focused on “it works” rather than modern USB convenience.
The Iomega 100MB External SCSI Zip Drive (Z100S2) is an external 100MB mechanical disk drive built for SCSI setups, with transfer rates typically cited around a few MB/s. It can be a practical choice for legacy workflows that still use Zip-style media, but it is not a plug-and-play option for modern laptops without SCSI support.
