Not only could you fit all of the major tech companies' data onto one gram of your DNA, but there would be room left over. It's estimated that a gram of DNA could hold 455 exabytes of data. (For reference, one exabyte is equivalent to one billion gigabytes.) DNA's longevity (in proper storage conditions) means that people could theoretically retrieve stored data after thousands of years with few, if any, errors. The main obstacle in the way of converting DNA into hard drives is the expense: synthesizing and sequencing DNA costs tens of thousands of dollars.
