THE DVD ADVANTAGE
DVDs provide a robust and flexible method for backup of your music projects. Costing less than $1.00, this storage option is our recommended solution for archiving all your audio and video files. DVDs have trumped CDs by packing much more capacity into the same 120 mm space as the CD. You can see below the advantages offered by DVDs over CDs.

DVDs use a tighter pit layout to sqeeze almost 7 times more data on a media the same physical size as the venerable CD-ROM. DVD and CD-ROM data disc needs protection against dust, particle contamination, water and heat. These factors cause damage to the data stored on the DVD. Prevent the DVD from being exposed to scratches which also can cause loss of data.
