Thanks Steve - an intersting article about the Vatican's project - good on them for being so forward thinking.
So, yes - an enormous amount of storage eh? - yes, 2.8PB is huge by today's standards. However, when I started in computing, 1MB was almost unimaginable. My first serious piece of commercial computing work was at Barclays Bank and there we had branch servers with 2GB Hard disks. Well, my phone has 4 times that, and even that is modest by today's standards!
The question I ask is this - how long will it be before we can store the whole of the Vatican's library on our hand-held devices?
By my reckoning, I'd say 10 years or less...
