Researchers can store data in DNA; the hard part is retrieving it
I was also intrigued by this comment in the article, “For example, an external hard drive about the size of a paperback book can back up 5TB of data and might last 50 years.” It seems that we have the ability to store information in DNA but no one knows exactly how long magnetic and digital storage will last. One thing is certain the last number that I read was 20 years for digital storage … so at least the number is going up.
