磁盘驱动调度对磁盘的效率有重要影响。磁盘驱动调度算法的好坏直接影响辅助存储器的效率，从而影响计算机系统的整体效率。

　　常用的磁盘驱动调度算法有：最简单的磁盘驱动调度算法是先入先出（FIFO）法。这种算法的实质是，总是严格按时间顺序对磁盘请求予以处理。算法实现简单、易于理解并且相对公平，不会发生进程饿死现象。但该算法可能会移动的柱面数较多并且会经常更换移动方向，效率有待提高。-Disk drive scheduling efficiency of the disk have a major impact. Disk drive scheduling algorithm will have a direct impact on the efficiency of secondary storage, thus affecting the overall efficiency of the computer system. Commonly used in disk drive scheduling algorithms are: simple disk drive scheduling algorithm is first in first out (FIFO) method. The essence of this algorithm always strictly chronological order of the disk requests to be addressed. Algorithm is simple, easy to understand and relatively fair, the process of starvation phenomenon does not occur. However, the algorithm is the number of cylinders may be more mobile and will often change the direction of movement, efficiency to be improved.
