NEW YORK GENOME CENTERYaniv Erlich and colleagues encoded large media files in DNA, copied the DNA multiple times, and still managed to retrieve the files without any errors, they reported in Science today (March 2). Compared with cassette tapes and 8 mm film, DNA is far less likely to become obsolete, and its storage density is roughly 215 petabytes of data per gram of genetic material, the researchers noted.
To test DNA’s media-storage capabilities, Erlich, an assistant professor of computer science at Columbia University in New York City, and Dina Zielinski, a senior associate scientist at the New York Genome Center, encoded six large files—including a French film and a computer operating system (OS), complete with word-processing software—into DNA. They then recovered the data from PCR-generated copies of that DNA. The Scientist spoke with Erlich about the study, and other potential data-storage applications for DNA.

. . . achieved a density of 215 petabytes per one gram of DNA. Your laptop has probably one terabyte. Multiply that by 200,000, and we could fit all that information into one gram of DNA.
Intelligent design? Very intelligent design!
