1. A method for achieving substantially average case hard disk drive transfer bandwidth in a video server system having a plurality of D hard disk drives whereon blocks of video movies are stored before transfer to a buffer unit, the method comprising the following steps:

  • (a) dividing each of said hard disk drives into Z substantially equal storage zones;

    (b) recording a portion of each of said video movies across all of said storage zones such that each of said storage zones contains a substantially equal number of blocks of a video movie; and

    (c) for said video server system, defining a substantially equal number of user streams per a slot using each of said zones, wherein a sum S of said user streams represents a maximum number of users that can access said video server system at one time;

    wherein worst case bandwidth for each slot is determinable given worst case bandwidth information for transfers from each said zone.
