DNA as a data carrier – Microsoft is leading the way

The world may soon have a data problem. Every day, 2.5 million gigabytes of them are created in the world, and every year this value increases significantly. Thus, it becomes a serious problem that we produce more data than we can store.

Science Magazine temper nature He predicts that if everything is stored in flash memory, it will use 10 to 100 times more silicon than expected by 2040. So obviously we need a different solution. A way to store data reliably for decades while reducing the size of data centers.

and doge Microsoft Our DNA would be a good mediator. It turns out that the nitrogenous bases (adenine, cytosine, guanine and thymine) contained in deoxyribonucleic acid can play the role of ones and zeros for data storage. Scientists predict that the DNA will contain no film ever made, less than a sugar cube. It is said to have a recording density capable of accommodating one exabyte per square inch.

However, one of the main issues with this solution is the slow write speed. This eliminates the use of DNA as a vector for frequently used data. Ignoring the technical difficulties of improving performance, is that too expensive at the moment? A few megabytes would cost thousands of dollars. It can take a long time to research this technology before you see the light of day.
