Why was gang labor a positive for slave owners?

The idea of a gang system is that enslaved workers would work all day (traditionally, from sunrise to sunset) under the supervision of an overseer. Breaks for lunch and dinner were part of the system. This is opposed to the task system, under which the worker is released when his assigned task for the day is completed.

It is the more brutal of two main types of labor systems. The other form, known as the task system, was less harsh and allowed the slaves more self-governance than the gang system did. The gang system allowed continuous work at the same pace throughout the day.
