Date storage growth by unit of Zettabytes, Video is the major factor

Since the starting of digital data storage, that is from 1957 to 2010 a total digital data of one Zettabyte is created, but now a digital data of Zettabyte is expected to be created in just one year from 2015 to 2016. You can see the massive amount of growth in digital data creation. The exponential growth is mainly due to growth in multimedia digital data creation, more of high definition video. IHS says a data of 413 Petabytes (PB) is produced in just one day by all the new video surveillance cameras installed worldwide in 2013. This is really the big data, compared to the megabytes and gigabytes created just a few years back. If you're in the storage industry, this is a very good news because there is a requirement of huge storage capacities both for personal as well as enterprise storage and also cloud. Though Flash memory density is increasing, and cost is falling, NAND flash memory not going to fill the demand gap. The magnetic disk storage will remain the main storage for some more years. Optical disk storage also continue to stay as important option for backup. At personal device level, the amount of storage in their own device is reduced but is stored elsewhere using cloud-based storage services. Irrespective of this trend, the per capita storage is growing exponentially. The growth of high definition video cameras use in Security surveillance is an impor...
