This is one of the best blog entries I’ve read in a while, despite the fact that it is in the form of an image, which I would normally frown upon.

The topic in hand is the progression from terabytes to the next level petabytes. It took me a while to get my head around this at first. A terabyte is a thousand gigabytes, a petabyte is a thousand terabytes. So, in other words, quite large.

One of the fascinating facts in the Mozy image helped visualise just how big this really is: “1G = 7 minutes of HD video. 1P = 13.3 years of HD video.”

The other scary fact was the amount of processing Google does. Mozy suggest that this is 20P a day, whilst the entire history of written work from man in any language is 50P. I know Google includes video, images, and all that jazz, but 20P per day boggles my mind.

Even so, I am still waiting for the yottabyte to come out, because firstly, how awesome is that name? And secondly, what comes after that?
