It's time for me to select a data format.
My data are (more or less) spectra ( a couple of thousand samples), six channels, each channel running around 10 Hz, collecting for a minute or so. Plus all the settings on the instrument.
I don't see any significant differences between netCDF4 and HDF5. Gary: netCDF4 is just a thin wrapper on top of HDF5 1.8 - think of it as a higher level API. Similarly, I don't see significant differences between pytables and h5py. Does one play better with numpy?

What are the best numpy solutions for netCDF4?
There's only one that I know of - http://code.google.com/p/netcdf4-python. -Jeff -- Jeffrey S.
