Restart vs datafile

I am curious, is there any significant difference if a simulation is run from the restart file(read_restart command) and when it is run from a restart file converted into a data file (read_data command)? If yes, why is this so?

Thanks

restart files contain more information than data files. it is all
explained in the documentation.
