Hi,<br><br> I have been using h5py a lot (both on windows and Mac OSX) and can only recommend it- haven't tried the other options though....<br><br> Cheers,<br> Simon<br><br><br><div class="gmail_quote">On Tue, Jun 21, 2011 at 8:24 PM, Derek Homeier <span dir="ltr"><<a href="mailto:derek@astro.physik.uni-goettingen.de">derek@astro.physik.uni-goettingen.de</a>></span> wrote:<br>

</div>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.<br>
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).<br>
