While this data set might not be considered "big" to a server farm responsible for thousands of users' data, for me, this is plenty big. My definition of big tends to be more like "some chunk that is hard to manage with the tools at hand, and is difficult and slow to transfer with the bandwidth available." Let's face it -- it's not trivial to just get what you need, when you need it. I pay my ISB a fee to handle the nominal flow of data in and out of my network. If I need more, I'm stuck. Likewise, my main machine is great for my day-to-day, but suffers when it processes something of this magnitude.
