The year is 1995, I am in a small computer shop, bringing back a harddrive. It is a 2 Gigabyte harddrive with bad sectors, that I am exchanging for a brand new, Fujitsu 5 Gigabyte monster. “Wow…that is the space I am not going to fill up for a loooong time”, a thought goes through my mind…Fast forward to 2010 and I am sitting here with my main computer sucking away it’s storage of more than 5 Terrabytes of data (albeit split across 6 harddrives). That’s a thousand times more and counting. If it keeps on ticking with a logarithmic progression I will be looking at 5 Petabytes around 2025. Or is it wishful thinking? (look, no flying cars yet!)
