It doesn't seem that long ago when I first heard of a 1GB drive being sold, and I thought to myself, "man, if I got one of those, I'd never run out of storage again..."
Now, of course, I can chew up 1GB in less than a day on a short field trip with my digital camera...
I am reminded of the page in an old (and I mean *old*) "PC Magazine", where they playfully "defined" various computer terms in funny or satirical ways. At the time, disk drives were about 20-40 megabytes, which seemed huge in those days, but people started noticing how fast even "huge" disk drives managed to get full. So the authors of the article decided to be over-the-top funny and defined "Terabyte" (which is a 1000 gigabytes) as "A unit of storage so unimaginably vast that it would take the average user two weeks to fill it up."
In those days, this was just ridiculously hilarious. Today, meanwhile, it's almost exactly true, given the speed at which we can generate digital images or video, and download entire seasons of TV programs, high-def movies, etc.
My friend: 'What would you do with a gig drive'
Me: 'Stack it!' (remember stacker?)
