The world’s stock of data grew 62 percent last year. According to The Guardian, we squirrelled away 0.8 zettabytes of data.
That’s 800,000 petabytes, where each petabyte is a million gigabytes. Somewhere along the way, we forgot about exabytes (1000 petabytes).
By the end of this year, we’ll be sitting on 1.2 Zb.
It is a lot of data.
But as previously reported, almost all the data stored around the world is junk. Experts say as much as 90% of stored data is useless.
We’re not talking about trash tv or bad music. We’re talking about data that is of no use to anyone; useless files, duplicate data, temporary files that became permanent.
Forget everything you hear from businesses selling virtualisation as a green technology. If the so-called green computer makers wanted to use less electricity and save the planet, they would work on tools to de-duplicate files and data and applications to help us cull rubbish from our hard drives.
This would also make it easier to find the good stuff.
