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.
At these file sizes, a DVD-R can hold about 2,200 pictures or around 1,100 MP3 files. Thatâs good for a disc, but itâs pretty mind-boggling when you look at how much more a Blu-ray disc holds. With a 25GB capacity (or 25,600 MB), a Blu-ray disc can hold up to 11.6 hours of DVD quality video. Thatâs over 9 hours more video on a Blu-ray disc than on a DVD disc at the same level of quality. Of course, most folks use Blu-ray discs for their intended purpose: high definition video.
