Spurred by 5G, we're headed into a new  zettabyte datasphere, say experts
By  Vishnu Anand
January 27 2019: A recent study by analysts at  IDC suggests that  we are headed towards a  data driven world, always on, always tracking, always monitoring, always listening, and always watching – because it will be always learning. Scary? Shades of Big Brother is Watching You? Get used to it:  the digitization of the world has begun.
In 2019: we'll be  generating and consuming even more data than before.
Remember those Hollywood thriller  movies, where a military guy, tackling a nuclear emergency yells: "We're at DEFCON 3"?   That's DEFence readiness  CONdition 3.|
Today they talk of DATACON  or Data readiness Condition.  They tell us the entertainment industry is at DATACON 2: Moviemakers  are discovering  that creating something virtually, is cheaper than creating the real thing … eventually eliminating the need to work with cranky live actors and actresses.  It's already happening  -- almost.Check out this video
MRI scans  have more images with thinner slices and 3D capability...  from 2,000 images to over 20,000 for an MRI of a human head. More data.
Finds IDC: Today, more than 5 billion consumers interact with data every day — by 2025, that number will be 6 billion, or 75% of the world's population. They're calling it the Global Datasphere  and  it will grow from 33 Zettabytes (ZB)  today  to 175 ZB by 2025.   Zetta is  one followed by 21 zeroes.
Seagate who sponsored the IDC study identify  three types of storage for all this data: solid state drives (SSDs) as found in phones, laptops and tablets; hard disk drives (HDDs) as  PCs still use -- and  Solid State Hybrid Drives (SSHD). They use solid state to deliver blazing  speed and bundle  it with hard disks for low cost and  high capacity.  
While consumers  like us,  in the upcoming 5G  phone era will enjoy the zippy speeds of   SSDs, enterprises still overwhelmingly bank on good old hard drives. And a masala mix of the two  is  taking us at breakneck speed into a zettabyte world.  Fasten your seat belts!
