Where did you get that data-point from? I've been told a single genome 
sequence takes up about 6 GB of data, and I think that's after it's been 
processed.

According to this article,  raw sequence can take up between 2-30 TB, 
and a processed one 1.5 GB. (Disclaimer: I only read the executive summary)
