Chemical Storage{5}

Computers and technology are growing at an astronomical rate, according to Moore the advancement of technology is doubling every 18 months and don’t we see it. This advancement is calling for an increase in the amount of storage due to the fact that everything we do on devices that use and store information. The rise of social networking and other business related needs are what is fueling this rise in information consumption. How do we as consumers of this extraordinarily large market of technology keep it growing. Well the answer to that is to keep developing. Like stated everything that we develop would need to be stored, which if we keep growing might become a problem. Due to the rising need for information storage capacity researchers at MIT and all over the world are looking into a new form of storage that has the potential to have unsurmountable data storage abilities. This new media is not in a conventional display, it is in a micro-structure, DNA.

As common knowledge DNA stands for Deoxy-Ribose Nucleic Acid which refers to the structure of the double helix molecule that is the basic building block of life. So what does DNA do? DNA is a genetic code that gives instructions to cells so they know what characteristics to have and what functions to carry out. It could be said that DNA is the code that let the cells(computer) carry out functions. One might begin to see the correlation between DNA and data storage. The different combinations of bases when interpreted can be likened to binary structure where different combinations of 1’s and 0’s carry out all logical decisions in code. For example the different sequences and appearances of the bases adenine and thymine, and guanine and cytosine are what would represent the one on and one off code that we call binary.

According to an article by Samuel Greengard for the Communication of the ACM gives insight into just how much data these molecules can actually store. He says that during a specific example they took a 54,000 word book and manage to store all of that information in 5.27 megabits which is at a storage density of 5.5 peta-bytes per cubic millimeter. For those that are not aware of the magnitude of this break through, a peta-byte is 1000 tera-bytes which is 1000 giga-bytes which is 1000 mega-bytes and so on. 1 peta byte is equivalent to 1.1259e15. That is a lot of data for one cubic millimeter of media. To put this in perspective as of right now production hard drives are at a storage density of a little less than a tera-byte per inch. So as one can clearly tell this is definitely a piece of research to keep an eye on.

Like with everything there is always a downside. As of right now the cost is the issue. According to an article by an MIT affiliated journal the cost of writing data to DNA is about $16,365 per megabyte. To write the amount of data that will max out the media with be 1,083,841,824 mb X $16,365. There is no mistake that this technology is not feasible to use in production however once there is a way to do this more efficiently and less expensive it will unlock potential never before imagined.

What does this have to do with databases? If we as consumers were able to fathom this much data we would need to create a new basis of the ways in which we store data. A version of SQL could possibly work however given the amount of data to sift through and retrieve there might need to be another form of organization. However once this get figured out we will be able to create data warehouses that can house historical data form the life of all companies many times over. Technologies like Apache Hadoop might be a thing of the past because all information will be present in one area.

While looking at the this new media as a possibility for greatness a lot of the kinks are still not worked out, for example how long does it take for DNA to decay and have to be reengineered? As well as how many times i can be read from before data gets corrupted. All of these things needs to get answered however when they do and if this media becomes able to be rapidly produced the whole industry and concept of information storage and gathering is going to change.
