About four grams of DNA theoretically could store the digital data humankind creates in one year.
These researchers have found they can store a zetabyte in a single gram of DNA. Storage methods usually happen on a plane, but DNA stores information in three-dimensional volume. Therefore, when compared to traditional techniques such as hard drives, the density of data that can be stored in DNA is immense.
This isn’t just theory; George Church and his team succeeded in encoding his ebook into DNA strands.
