Using chemical-based memory devices for large scale data storage

Ninety percent of the data in the world today has been created in the last two years alone. Our current output of data is roughly 2.5 quintillion bytes a day. A quintillion is a number followed by 18 zeros. It’s a lot. It was generally used to refer to the mass of the earth (in tons) and the number of molecules in the human brain.  And now it’s being used to help define how much data is being produced by all of our internet activity through each uploaded picture, tweet tweeted, or study published. As the world steadily becomes more connected with an ever-increasing number of electronic devices, the amount of data generated will only grow over the coming years. As such, there will be increasing challenges on how to store all this “stuff” in an efficient manner. More of the same technology may not be the answer. This Science Café will describe a new approach to data storage using polymer films and a quaternary code of 0, 1, 2, 3.  This is in contrast to data storage as currently realized, in a binary code of 0 and 1. The expansion to a quaternary code allows for substantially more data to be stored in the same space, and can be likened to the code that Nature uses to store data in DNA: A, C, T, G. Current limitations, approaches to overcome, and other such hurdles will also be addressed at this Science Cafe Cleveland.
