I remember when I purchased a 3GB HDD for over $300. That was years ago. Today, you can find one with the capacity of 750GB for under $150. I actually got an ad for a 500GB drive for $99. Now that's a major difference! And of course today you can find external space on many different platforms, such as USB key. So let me ask you all this question: How many external devices do you own that you use to store your data - other than an internal HDD?
