I took it from the referenced article.  yes, various organisms
have different sized genomes, but size doesn't correspond that much
with intuition.  I'd also claim that 6GB is still small - 
certainly not going to drive some kind of dramatic burst of storage sales.

nice article, though the big-raw-data thing is very much a consequence
of the short-read technique afaik.  the direct-read-through-pore approach 
is vastly more parsimonious.
