(a) The benefits of short stroking. (b) The benefits of short stroking, decomposed into components: () reduced arrival rate into each disk; () less seek time since fewer tracks are used; () faster data access at larger radii. For this plot cm, cm, cm/ms, and the disk spins at 7200 RPM disk. Each request is for 50 cm of physical track length, and the scheduling policy is C-SCAN.
