I'm in the process of finishing up the replacement an ailing 250GB hard, moving all my data from it (and various other places I had to pull data over to before the old drive had a chance to mangle anything of importance) onto a shiny new 2TB drive -- an 8x jump in capacity.
Moving to this new drive got me thinking about how much capacity I now have in relation to the first PC I ever owned exactly 20 years ago: My first PC was a homebrew (I never buy brand name PCs) 486 DX-33, sporting 4MB of RAM and a 20MB hard drive -- 1/100000th the size of my current drive!.
Hell, my phone has more storage capacity than my first PC ever did...and vastly more processing power to boot.
I'm always amazed at how much technology changes through the years. Not everyone likes the pace of change, but I find it exciting. There's rarely a dull moment in our industry.
