We have spent several years testing MO, CD, and especially the new DVD technology. Most storage devices are shamefully overpriced. A Zip drive is handy to switch files among computers within your office and almost essential to send material to other people. This is because almost all professional graphics people have a Zip drive available. But avoid the temptation to use Zip disks for long term storage.
Zip disks are needlessly costly.
Zip disks cannot store enough data to make them cost-effective, not even the newer larger Zip size. DVD , the best solution for now and into the new millenium. CD-R , the best budget solution now and for the next years.
