I could also recommend using NetCDF 4 files, which are quite flexible
and really fast to write/read. I made a small workbench test to write
and read a [500,500,500] array. Funny enough, both file have same size
on disk (477.8 Mb) but the IN/OUT differences are striking:

% Time elapsed IDL save: 8.8444729 seconds.
% Time elapsed NCDF save: 0.57288098 seconds.
% Time elapsed IDL restore: 8.8600481 seconds.
% Time elapsed NCDF restore: 0.63916397 seconds.
