For the same force between the disc and pads, larger discs generate more torque on the wheel - equating to more stopping force. While this is great, it's also generating more friction for the same pressure and increase pad wear.
In addition, larger discs have a larger surface area, dissipating more of the generated heat, allowing discs and brakes to stay cooler and reduce braking fade.
