I use netCDF (which uses the HDF5 libraries netCDF4).  NetCDF is good  
for large, gridded datasets, where the grid does not change in time.   
For my datasets (numerical ocean models), this format is perfect.

HDF is more general and flexible, but a bit more complex.  Take a look  
at the netcdf4-python.googlecode.com package, if you are interested.
