SSD controller, data processing method and device and storage medium

The invention relates to the technical field of storage, and discloses an SSD (Solid State Disk) controller, a data processing method, equipment and a storage medium. The device comprises a control module used for judging whether to search a flash memory of the SSD or not according to the number of to-be-recycled data blocks in a forced recycling pool when the SSD is powered on; when it is judged that the flash memory is searched, a search instruction is generated and issued to the search module; the to-be-recycled data blocks are data blocks of which the data storage time is greater than or equal to a recycling threshold value; and the search module is used for searching all the data blocks in the flash memory in response to the received search instruction. The SSD flash memory is searched on the basis of the device, occupation of a CPU clock period can be reduced, and the running performance of the SSD is improved. 本申请涉及存储技术领域，公开了一种SSD控制器、数据处理方法、设备及存储介质。该装置包括：控制模块，用于当SSD上电时，根据强制回收池中待回收的数据块的数量，判断是否对SSD的闪存进行搜
