In the real world, the popularity of each video is different. We propose a new popularity-based data allocation scheme to allocate data units within a cluster such that the corresponding data units of these popular videos are stored in those cylinders at one end of each cluster. Due to a higher spatial locality within these "hot" cylinders, some data units requested by the users are stored in the same cylinder such that one seek operation, one rotation, and one transfer operation are required to retrieve data units to be played. Therefore, the time required to retrieve data for these requests can be reduced, thus reducing the system response time as well. Based on our results, the system response time could be reduced by half or more.
