If you don't mind anecdata: I'm in the third year of my PhD and would classify myself as an average hard worker compared to my peers. It is highly improbable for someone to work three times as hard as an average PhD in any half-decent program. A lot depends on your adviser but anyone serious about their work will demand a certain level of output from their grad student (like any other manager situation) which necessitates a certain level of work. PhDs and post-docs are notoriously underpaid for the amount of work they do.
