A Petabyte on a DVD
According to a recent article on Science Daily (one of my favorite retreats for reviews on journal articles from physics and computer science to sociology and psychology), a “full 90% of all the data in the world has been generated over the last two years.” This truly is amazing information.
Apparently, this comes as a direct result from “big data” research centers at organizations like Google and Facebook. These companies process a staggering amount of data while amassing and analyzing meta data on what we’re doing and looking for.
As you may or may not know a standard DVD (not Blu-ray) holds 4.7 GB of data. Scientists have recently shown this can be increased to a Petabyte, or 1,000 TBs on a single DVD. In its simplest terms the researchers humpbacked two laser beams in what they call “electron beam lithography,” which in effect allowed for 3D writing. The technology allows for the writing of information on a nanoscale never before achieved.
“The technique is also cost-effective and portable, as only conventional optical and laser elements are used, and allows for the development of optical data storage with long life and low energy consumption, which could be an ideal platform for a Big Data center.”
Aside from DVDs, it will undoubtedly have impacts on all forms of storage and processing. Is this the way of the future? What do you think will become of Blu-ray discs? I would love to hear what our readers think of yet another potential shift in the medium for which we store our data.
