I must admit I prefer h5py, even for small amounts of data. The tree
like structure of the data makes organizing your arrays so much
easier.

>>> import h5py
>>> f = h5py.File('example.hdf5', 'w')
>>> import numpy
>>> f['my_array'] = numpy.arange(10)
>>> f.close()

Almost as easy to use as numpy.save(), too.

Cheers,
Paul
