DVD-R's hold 4,700 MB of data, a little more than 7 times that of CD-R's. Higher Order Cost: CD-R's hold fewer photos than DVD-R's. More disks will be needed if your placing a large order. Lower Order Cost: Because DVD-R's hold more photos you will need fewer disks when placing a large scanning order.
There are four types of DVDs: 1. Single-sided discs that hold one layer of data 2. Double-sided discs that hold one layer of data on each side 3. Single-layer discs that hold two layers of data 4. Double-sided discs that hold two layers of data on each side To utilize dual-layer technology, you must have both a compatible disc writer and dual-layer media. The actual number of files you can archive (or burn) on a disc varies depending on the quality level of saved files.
