o Removing data from the internal memory is a slow process, so it is better to keep the files small
and remove them soon after data logging is complete. In the current software, downloading 1GB
of data requires approximately 1.5 hrs. File sizes are accumulated based on the number and
frequency of messages scheduled to log. At 1Hz, a typical log file used for survey purposes will
be about 20MB.
