Thanks, Tony.

That article is nice in that it makes explicit comparisons to known big
datasets; for many folks (myself included), talk of exabytes is simply hard
to fathom out-of-context.

There is a very active field of research working to address the data growth
issue in genomics.  A few recent papers give overviews and implementations
of compression.  Beyond compression, graph-based genomes offer incredible
benefits for data processing as well as compression.

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4479802/

The latter link describes a compression strategy for genomics data of ~9500
fold.

I saw a talk about this approach and the authors suggested that their
testing of graph-based genome encoding could lead to 100k genomes being
stored in 16GB (unpublished, as far as I know).

Of course, the devil is in the details, but the data sizes doomsday
articles quote do not often directly address the incredible opportunities
for compression that exist for genomics data.  The reason for slow adoption
of these compression strategies is that the compressed data need to be
ingested by other tools to be useful and tools that do so don't exist yet.
If a compression standard emerges or we get a graph-based genomic standard,
we may see storage issues become less concerning and will, instead, inherit
a new set of analytical and data processing opportunities and challenges.
