Segments in this Video

Data Storage: Introduction and History (02:55)


Herman Hollerith invented the punch card in 1884; magnetic tape was applied to data storage in 1951. Other data advances included compact cassettes in 1963, floppy disks in 1969, compact discs in 1982, DVDs in 1992, and flash drives in 1999.

Bioinformatics (04:14)

Nick Goldman studies DNA; he converts binary code into genetic nucleic acids. Financial challenges prohibit the technology's expedient development. Emily Hesketh explains how the sequencing machine transforms information.

Physical Optoelectronics (04:21)

Physicist Peter Kazansky uses lasers to create nanostructures in glass. The discs he creates are extremely resilient and can potentially last billions of years.

2.5 quintillion—this is the number of bytes of data we produce globally every day. The classic large server rooms we're used to seeing are no longer viable, so the race is on to find a way to store more data in less space. We explore two approaches to the future of data storage: firstly with a visit to Cambridge to see how a European-wide group of scientists is using synthetic DNA to store data, and the potential is mind-boggling—you could store 2.2 million gigabytes in two grams of DNA, or put another way, all the digital information on the planet in a shoebox. DNA is stable to a point and can last for thousands of years, but a group of scientists in Southampton have developed a way of transferring information into glass in a five-dimensional shape. You could store 360,000 GB in a tiny sliver of glass and it could last for billions of years.
