A DVD or Blu ray disc's can be either single or dual layered which refers to how much information can be held on the disc. A single layered DVD can hold 4.7 GB of information while a dual layered DVD has a storage capacity if 8.5 GB. A Blu ray disc can hold approximately five times more the information on a single layer with a capacity of 25 GB and the dual layer Blu Ray can hold 50 GB of information.
