Abstract
A storage device is provided. The storage device includes a control unit, a hot spare area, and a data area. Because a quantity of bits that can be stored in a second-level storage unit corresponding to the hot spare area is less than a quantity of bits that can be stored in a first-level storage unit corresponding to the data area, data read/write performance of the hot spare area is higher than data read/write performance of the data area. In a data access process, the storage device temporarily stores target data in the hot spare area, and a data read/write speed of the storage device is consistent with a data read/write speed of the hot spare area. This improves data access efficiency of the storage device.
