There are many forms of information storages. Unlike them DNA is terrifically long-lasting and does not require constant electrical power, it is tiny and a small cup of DNA can store one hundred million hours of HD video. What else do you need?
We ordinary people do not use DNA storage. Because DNA synthesis is very expensive and only works for short strings. But scientists have used synthetic DNA to store digital files.
British researchers broke a long string of information into many overlapping short sequences, each tagged with its position in the overall sequence. American collaborators then synthesized short pieces of DNA to match the strings, and shipped the material overseas. Finally, researchers reconstructed the digital files with complete accuracy.
From what I understand is, it will take a decade to make DNA storage cost-effective. I really hope it happens in my lifetime. I just can’t wait to use it.
