The invention discloses an SSD controller, a solid state disk and a data processing method, and the SSD controller comprises a preprocessing state machine which is used for obtaining a command issued by an NAND Flash controller for an NAND Flash memory, and correspondingly issuing the command to a first cache or a second cache according to the type of the command; the first cache is used for storing the SCA command issued by the preprocessing state machine; the second cache is used for storing a data transmission command issued by the preprocessing state machine; the first state machine is used for processing the command in the first cache; and the second state machine is used for processing the command in the second cache. Therefore, on the basis of being compatible with the original Legacy interface, the SCA interface is supported, so that the data transmission efficiency is improved, and the read-write delay is reduced. 本申请公开了一种SSD控制器、固态硬盘及数据处理方法，所述SSD控制器包括：预处理状态机，用于获取NAND Flash控制器针对NAND Flash存储器下发的命令，并根据所
