SLOW DISK DRIVE DETECTION METHOD AND APPARATUS, AND ELECTRONIC DEVICE AND STORAGE MEDIUM

Provided in the embodiments of the present application are a slow disk drive detection method and apparatus, and an electronic device and a storage medium. In the embodiments of the present application, when a response to an I/O request issued by an upper-layer application for accessing a hard disk drive is slow, the hard disk drive that the I/O request is used for accessing is not directly disabled, but a slow disk drive category of the hard disk drive that the I/O request is used for accessing is distinguished according to the duration of the slow response to the I/O request, the reason why the hard disk drive is slow is analyzed in a targeted manner on the basis of hard disk drives of different slow disk drive categories, and a usage state of the hard disk drive is controlled according to the reason why the hard disk drive is slow. Therefore, the reason for a slow disk drive is accurately and quickly diagnosed, and a hard disk drive that an I/O request is used for accessing cannot be directly disabled with
