Abstract
A data migration method and a storage device are provided. The device obtains data access temperature of a first storage unit group, which is determined by data access temperature of each storage unit, and the data access temperature of each storage unit is determined by a logical unit in which the storage unit is located. When the data access temperature of the first storage unit group reaches a specified threshold, the storage device migrates data in the first storage unit group to a second storage unit group. Access performance of the second storage unit group is higher than access performance of the first storage unit group. According to this application, accuracy of collecting statistics about data access temperature can be improved, thereby improving hierarchical storage performance of a storage device.
