Abstract
Embodiments of the present disclosure provide a disk area isolation method, where the method includes: receiving, by a file system, a request for access to a file, where the access includes file reading or file writing; determining a to-be-accessed data block according to the request; accessing a physical area corresponding to the data block on a disk; identifying, according to a time consumed for accessing the physical area, whether the data block is located in a low-speed area on the disk; and isolating the data block that is identified to be located in the low-speed area.
