I was about to point you to this discussion:
but I see that you participated in it.
I store data from each of my experimental run with pytables. What I like
about it is the hierarchical organization of the data which allows me to
save a complete description of the experiment, with strings, and
extensible data structures. Another thing I like is that I can load this
in Matlab (I can provide enhanced script for hdf5, if somebody wants
them), and I think it is possible to read hdf5 in Origin. I don't use
these software, but some colleagues do.
So I think the choices between pytables and cPickle boils down to whether
you want to share the data with other software than Python or not.
