1. In a data storage device including a disk, a method for controlling a spin-speed at which an initial data transfer occurs after the disk begins to spin-up from rest, the method comprising:

  • (a) spinning the disk up to a reduced spin-speed and beginning to perform the initial data transfer while the disk spins at the reduced spin-speed, if an initial amount of work that has been requested is below a threshold; and

    (b) spinning the disk up to a further spin-speed, which is greater than the reduced spin-speed, and beginning to perform the initial data transfer while the disk spins at said further spin-speed, if the initial amount of work that has been requested is above said threshold.
