+# Automatically splitting large data across multiple HDF5 files
+# -------------------------------------------------------------------
+#
+# For extremely large datasets it can be useful to split data across multiple files, e.g., in cases where
+# the file stystem does not allow for large files. While we can achieve this by writing different
+# components (e.g., :py:meth:`~pynwb.base.TimeSeries`)  to different files as described above,
+# this option does not allow splitting data from single datasets. An alternative option is to use the
+# ``family`` driver in ``h5py`` to automatically split the NWB file into a collection of many HDF5 files.
+# The ``family`` driver stores the file on disk as a series of fixed-length chunks (each in its own file).
+# In practice, to write very large arrays, we can combine this approach with :ref:`iterative_write` to
+# avoid having to load all data into memory. In the example shown here we use a manual approach to
+# iterative write by using :py:class:`~hdmf.backends.hdf5.h5_utils.H5DataIO` to create an empty dataset and
+# then filling in the data afterward.
