In my experience, HDF5 access usually approaches disk access speed, and random
access to sub-datasets should be significantly faster than reading in the
entire file, though I have not been able to test this.
I have not heard about pyhdf5io (how does it work together with numpy?) - as
alternative to h5py I'd rather recommend pytables, though I prefer the former
for its cleaner/simpler interface (but that probably depends on your
programming habits).
