摘要： This application provides a storage controller, a storage control method, a solid state disk, and a storage system. The storage controller includes a processor, and a first interface and a memory that are separately coupled to the processor. The first interface is configured to receive a data write instruction, where the data write instruction is used to request to write target data into a first logical address. The processor is configured to read, from the memory, a hotspot attribute corresponding to the first logical address. If the hotspot attribute indicates that the first logical address is a hotspot address, the processor is further configured to store the target data in a first area of the memory. The first area is used to replace storage space that is corresponding to the hotspot address and that is in a flash memory controlled by the storage controller to store data. While the storage controller prevents some very small LBA areas from being frequently written, to ensure that a service life of the solid state disk is not affected, a host side does not need to participate, and the host side does not need to adapt to the solid state disk. Therefore, a coupling degree between the host and the solid state disk can be greatly reduced.
