Just to wade in on this, RAID (Redundant Array of Inexpensive Disks) is usefull for a production environment, IF there is a back up program with those back ups stored off site.I work for a state attorney general, and we don't have thousands of images, we have millions, TIFF images stored on CDs. This is an archival function as these images are used for research. Magnetic media is OK, but it makes optical look stable.
One word of caution about zip drives, it is a proprietary technology, CD-Rs can be used with a variety of CD drives.
