CD’s typically hold a maximum of about 700 megabytes of information, while a DVD usually holds a maximum of 4 gigabytes. Usually a cd can hold approximately 300 – 1000 images, while a DVD is capable of holding thousands of images. The choice is yours, but personally we prefer high quality DVD’s or flash drives (will work in computers, laptops and tablets that do not have a CD/DVD Drive)For reference, comparatively, a 16 gigabyte flash drive holds four times the amount of a DVD.
