Only three days, and the question is resolved... THANKS for all the responses. Short version: the Zips didn't have a chance... not a single voice in favor of Zip for image storage - for lots of good reasons, including deterioration and other archival issues as well as space limitations. And no, I do not work for Iomega... in fact, my Zip clicked to death last summer... I've attached a summary of all responses as a .txt file - let me know if you can't open it and I'll send the whole thing in an e-mail message. Thanks again - I feel so much more confident choosing between all the options out there. Laura Bajuk, ED Los Gatos Museum Assn. ___ Sample response: From: [log in to unmask] (Tom Judd) A Zip drive is way too small for storing image files. You will fill it up very quickly. There are 3 alternatives: 1. Jaz drive, either 1 or 2 Gig. The least hassle, works just like a hard drive. Expensive media. Not entirely safe for archiving, because it can be erased. Also, the cartridges are mechanical so subject to failure. However, I have used Jaz for several years with excellent results. 2. CDR Very cheap media. 650 meg enough for most purposes. Universal format, especially ISO9660 format. Best for archiving because they can't be erased. Get a good writer such as Plextor. 3. CDRW Media now about the same as CDR. Not as good for archiving because can be erased. Problem to read on some machines. I use Jaz for short-term backups and storage. CDR for long-term.
