| Zusammenfassung: | A method for dynamically managing host read operation and read refresh operation in a storage device, a storage device and a storage medium thereof are provided. The method includes: controlling, by a controller of the storage device, a ratio of the number of host read operation to the number of read refresh operation in the storage device to be in line with a first value and obtaining a total read request count which accumulates in the storage device; when a criterion for updating the ratio is satisfied, determining, by the controller, a second value for the ratio of the number of host read operation to the number of read refresh operation according to the total read request count and information of blocks to be refreshed in the storage device; and controlling, by the controller, the number of host read operation and the number of read refresh operation so that a ratio of the number of host read operation to the number of read refresh operation is in line with the second value. |
