Slow disk detection method and device, electronic equipment and storage medium

The embodiment of the invention provides a slow disk detection method and device, electronic equipment and a storage medium. In the embodiment of the invention, when the response of the I/O request for accessing the hard disk issued by the upper-layer application is slow, the hard disk accessed by the I/O request is not directly forbidden, but the slow disk type of the hard disk accessed by the I/O request is distinguished according to the slow response duration of the I/O request; and based on the hard disks of different slow disk categories, analyzing the slow disk reasons of the hard disks in a targeted manner, and controlling the use states of the hard disks according to the slow disk reasons of the hard disks. Therefore, the slow disk reason is accurately and quickly diagnosed, the hard disk accessed by the I/O request is not directly disabled without distinguishing, and the influence on the data processing performance of the upper application is reduced. 本申请实施例提供一种慢盘检测方法、装置、电子设备及存储介质。在本申请实施例中，在上层应用下发的访问
