An other really important point is that you can easily import the
pytables files from other languages, such as C (I am using pytables/hdf5
to transfer data between python and matlab), which may be crucial
depending on your working environment.

I am not sure it is possible with "pure scipy" methods (at least in a
reasonable way). I may be totally wrong, though, as I don't much on the
implementation of the array protocol in scipy, and on the write/read
