Figure 6: (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.
