In this paper we examine the crystal nucleation rate of hard spheres using three such numerical techniques: molecular dynamics, forward flux sampling and a Bennett-Chandler type theory where the nucleation barrier is determined using umbrella sampling simulations. The resulting nucleation rates are compared with the experimental rates of Harland and Van Megen [J. L. Harland and W. van Megen, Phys. Rev. E 55, 3054 (1997)], Sinn et al. [C. Sinn et al., Prog.
