Apparently scientists have been working in the lab on a way to store media in DNA rather than traditional hard-drives. In many ways the format would be convienient. Unlike hard-drive DNA can store thousands upon thousands of documents within one strain. Also, DNA does not have to be updated. Hard-drives can be difficult to work with and often lose important data in transfers, or due to old age.
Sadly DNA compaction is to expensive to set into place during this decade; however, researchers in the U.K. and U.S. report that within the next few decades the price will be plenty more affordable. They even predict it may be as cheap as hard-drive today.
