In relating rotational vibration stimuli of a mechanical mounting environment to the performance of a disc drive, a method and system are provided of which the steps are selecting a sample disc drive of a drive species and mounting the sample disc drive within the mechanical mounting environment; attaching an accelerometer to the sample disc drive for measuring rotational vibration; inducing a predetermined rotational vibration stimuli into the mechanical mounting; collecting vibration data with the accelerometer for use in determining the rotational vibration index for the mechanical mounting environment; providing a rotational vibration index for the drive species for comparison with the determined rotational vibration index; and comparing the rotational vibration index calculated for the mechanical mounting environment with the rotational vibration index of the drive species to relate the rotational vibration stimuli of the mechanical mounting environment to the performance of the sample disc drive.
