Some say we’re now in the Terabyte Era, due to the size of today’s largest disk drives - two terabytes.
Others say we’re in the Petabyte Era (1,000x larger than a terabyte), since that’s about how much many companies now have stored in their datacenters.
Listening to IDC and EMC, one might think we’re in the Exabyte Era (1,000x larger than a petabyte). They calculate the sum of all digital data on the planet to be in the hundreds of exabytes.
Cisco seems to think that it’s the Zettabyte Era (1,000x larger than an exabyte), based on the volume of worldwide IP traffic by 2013 – over half of which will be video.
To each his own. Any way you slice it, our world is filling up with data.
By the way, it would take 500 million two terabyte Barracuda LP drives to store a zettabyte of data.
Who can tell me what comes after a zettabyte?
For extra credit, give me a reason to name an Era after it.
