Zip Disks

Zip Disks
Zip® Disks, introduced by the Iomega corporation, have become a de-facto standard for transportable data storage. Being physically a little large than a 3.5' floppy disk, and yet able to store 250MB (or 100MB in older versions), makes the Zip® Disk an excellent choice for both transportable media and also security backups.

However, it is precisely because such large amounts of data may be easily copied and transported, that the use of such devices needs to be carefully controlled within the organization. Please be aware that, only 10 years ago, 250MB was equivalent to the total storage capacity of most organization's data, and whilst this may appear small by today's standards, it's capacity ensure that ensure client databases, product details, plans and charts etc, can be reliably copied onto a disk that fits into a shirt pocket.
