When I was young, I did site networking at a large campus for a major tech company. One day, we were working in the warehouse area and saw pallets of brand new, state of the art, 4.7GB hard drives being unloaded. Being the nerds we were, my coworkers and I stood around staring wide-eyed at the loot we beheld before us. These weren't yet available for purchasing by the public, and we were in awe! They seemed almost magical.
For the next couple of days, the topic of HDD space was prevalent in our discussions. "That's almost limitless space!" "You could spend the next several years downloading and never fill that up!" When I finally got my hands on one of them, I was in nerd heaven. I thought I'd never need more space in my life.
Fast forward to today: I can download more than 4.7GB in a few minutes and I'm sitting on 150TB+ of HDDs. Technology advancement is crazy.
