The use of DNA as a storage medium for the general public is no longer science fiction, but a future that is fast approaching. Researchers have developed a prototype 100 times faster than currently available technologies, capable of writing 20 gigabytes in a day.
The use of DNA asposes a problem because of the writing. Current technologies have managed to write a maximum of 200 megabytes, an operation that took a whole day. The new chip developed by GTRI measures approximately 2.5 centimeters. The prototype integrates multiple microwells, with a depth of around one hundred , to write several strands in parallel. Once fully functional, the chip could be 100 times faster than other technologies.
A storage medium that could last for millennia
The data is encoded in the(A, C, G and T), but writing and reading results in up to 10% errors. To compensate, they also created a codec capable of identifying and correcting these errors in collaboration with the University of Washington.
This technology would not replace our hard drives in the near future, but rather serve as an archival medium. Currently, this operation is always carried out on, an old technology whose supports must be changed every ten years. At a sufficiently low temperature, DNA can be stored , thus providing a very long-term storage solution.
