One good reason to store copies of your important records on DVDs. The Guide of  DVDAid ,

A DVD has a life span between 20 and 100 years, and that’s one good reason to store copies of your important records on DVDs. Some things are priceless: Photos of a smiling college graduate or a homemade video of a tiny kitten, an enormous dog and a parrot with an attitude that collects a million hits on YouTube. Some things stored as digital data that would never go viral may actually be much more valuable than many people realize. Digital copies of important documents–such as financial records and family milestones–are not typically considered premium content in the same way that blockbuster movies are. Yet, if those digital family heirlooms are damaged in a fire or flood, the loss may be irreplaceable.
