A method of controlling an actuator in a disc drive to perform a seek operation prior to a read operation is disclosed. A radial distance between the initial track and the target track is determined. A rotational distance between the initial head rotational position and the target rotational position is also determined. The magnitude of the performance benefit to be gained by reading pre-fetch and post-fetch data is estimated. Then a seek velocity profile is selected based on the radial distance, the rotational distance and the estimated magnitude of the performance benefit that would be gained by reading pre-fetch and post-fetch data. The actuator then is controlled using the selected seek profile. A disc drive for implementing this method is also provided.
