Raw digital videofiles are very large (like 70-100MB). They usually don't
fit on one disk. Some options are: Zip drives or Magneto Optical drives. Zip
disks store 100MB and MO disks store 1.3 gig. You can also use a server
for storage. Compression will make the files smaller, but still anticipate them
be relatively large. There are no absolutes and file size depends on the content
