Here's something interesting, scientists in Europe have found a way to add 2.2 petabyte of data to synthetic DNA and retrieve it at 100 percent accuracy; however, we doubt this was easy to accomplish, like adding data to a hard drive.

The 2.2 petabyte of data was placed on a single gram of DNA, which is quite a small amount when you look into how much 2.2 petabyte of data really is. The scientists managed to encode Martin Luther King Jr.'s historic "I Have a Dream" speech and 154 Shakespeare sonnets MP3 on a string of DNA. To reach the 2.2 petabyte limit, the content had to be scaled up.

One big surprise here is how these scientists managed to achieve all this while implementing error correction. It's all just quite amazing, something you only see in some over-the-top futuristic movie that stands no chance of doing well at the box office.

At the end of the day, this process is incredibly expensive. So while you may be in awe and secretly hoping to purchase a storage device like this someday, you may want to come back down to earth and keep investing in current storage medias that are cheap and known to work. Who knows, the scientists may just be wasting tax payers' dollars on a technology that may never see the light of day in the hands of consumers. But then, that's called technological innovation.

Right now, we want something that is more practical than storing data on DNA. How about storing data in our brain and then retrieving that data by looking at a computer screen. The data would travel through our eyes and then project itself on the display. That's true innovation right there.
