技术领域technical field
本发明涉及计算机技术领域，尤其涉及一种磁盘的突发性访问识别方法。The invention relates to the technical field of computers, in particular to a sudden access identification method of a disk.
背景技术Background technique
磁盘是用于存储计算机数据的一种载体，存储在磁盘中的数据可以反复使用。而随着计算机的运算速度和数据处理速度的增长，人们在操作磁盘存储/读取文件的同时，也会执行其他的操作。这些操作对于磁盘来说属于突发性访问，传统的磁盘在面对突发性访问时，其感知方面存在不足，不能及时的进行处理，造成不必要的磁盘能耗。A disk is a carrier used to store computer data, and the data stored on the disk can be used repeatedly. With the increase of computing speed and data processing speed of computers, people will also perform other operations while operating disk storage/reading files. These operations are sudden accesses for disks. Traditional disks have insufficient perception in the face of sudden accesses and cannot process them in a timely manner, resulting in unnecessary disk energy consumption.
