You will increase speed and save disk space (generally) by
using binary files.

Also, if dealing with multiple 3-d data sets (eg. a timeseries
of a 3-d field) or to extract regions from disk quickly,
(random access binary files), look into the netcdf routines.
They are also available from idl, FORTRAN, and C.
