Introduction

Only a few years ago, many of these storage systems would have been called backup systems, but this time is about to be over. With hard drive capacity going beyond 20 GB, one will need dozens of a given media for data backup.
Still, many useful applications, documents, spreadsheets, and even medium size databases could fit on 40 MB to 2 GB of removable medium.
The choice of removable magnetic media can be quite straightforward and defined by the number 10. You should try to fit all the data you are going to move on not much more then 10 disks of your choice. More disks means more volume and more hustle, and it also means you should upgrade to a system with higher storage capacity.
If the amount of data you are planning to move around could fit on 5 storage units of your choice, you don't need larger, and generally speaking more expensive storage. For example, if you are planning to move MS Word documents, MS Excel spreadsheets, or other similar documents, a few 40 MB Click disks, 100 MB Zip disks or 120 MB Superdisks (by Imation Co.) will meet your needs. Increasing demand for storage will force you to migrate to the 250 MB Zip drive (which, by the way, can read 100 MB disks as well), and later, to the 1 GB or 2 GB Jaz drive (Warning! The 2 GB Jaz drive does not read 1 GB disks and could be damaged by them).
If you want to save space on your computer and have somewhat faster data access, you may consider Sony's alternative drive, which reads both 1.44 MB floppies and 200 MB disks. You won't pay much more then for a 100 MB Zip drive, but you may experience problems with compatibility. Few people have Sony HiFD drives, while Iomega sold more than 22 million 100 MB drives by the year 1999 and the Zip drive is almost a standard for today's PCs.
Imation Co. Superdisks offer an interesting option, allowing you to password-encrypt your data and combine encrypted and regular files on the same disk: encrypted files will simply be hidden.
Today, Iomega has a lead in the 100-2000 GB removable storage market, but the future of this multi-billion dollar market will depend on which technology is finally accepted and promoted by OEMs (original equipment manufacturers). If the sales of Superdisk and HiFD products do not grow robustly in the near future, they may never become widely accepted...
