Global annual internet traffic is expected to surpass one zettabyte in 2016. The zettabyte (ZB) was once reserved for measurements of the digital universe as a whole. Now, due to the surge of video traffic, new content creation, and mobile internet usage, the zettabyte has become part of our shared techno-speak, like the megabyte and gigabyte before it. To put a ZB into perspective: One million gigabytes = 1 petabyte. 1 million petabytes = 1 zettabyte. Some recently reported facts on the ZB:
• The entire digital universe is 4.4 ZB
(Source: International Data Corporation’s Digital Universe Study, 2014)
• One ZB can hold 36 million years of HD video
(Source: The Guardian newspaper, 2015)
Another way to visualize the scale of a zettabyte: According to Cisco Systems, if 1 gigabyte is equal to an 11-ounce coffee, then 1 zettabyte would have the same coffee volume as the Great Wall of China.
