Operating System

To simplify our explanations about magnetic disk access speeds, in this chapter, we use rotation speeds of 3,600 rpm and sustained data transfer rates on the order of one megabyte per second. However, current technology has pushed those numbers higher. Research current rotation speeds and data transfer rates for magnetic disks. Cite your sources, dates of the published research, and the type of computer (laptop, desktop, and so on) that uses the disk.
