HDF5 is a community standard file format that is fast and handles arbitrarily large datasets. HDF5 may be thought of as a filesystem withing a file, with access from most popular data science languages, including C, C++, Fortran, Julia Matlab, Python, R, etc. NetCDF4 is built upon HDF5 and is popular in the geoscience community.
