The invention provides a mixed hard disk controller which comprises a hard disk interface, a data safety module, a data management module, a solid state storage controller and a microprocessor. The data safety module is connected with the hard disk interface and the data management module. When the data safety module receives data sent from the hard disk interface, the received data are encrypted first, and then the received data are sent to the data management module. When the data safety module receives data sent from the data management module, the received data are decrypted first, and then the data are sent to the hard disk interface. The data management module is used for carrying out statistics on the reading-writing frequency of data and dispatching the storage position of the data in a storage unit according to the reading-writing frequency of the data. According to the technical scheme, safety of stored information is greatly improved, meanwhile, data encryption work is completed by hardware, CPU resources do not need to be consumed, meanwhile, transmission bandwidth is not affected, and the overall performance of an application system is improved.
Description
technical field [0001] The invention relates to a hard disk controller, in particular to a hybrid hard disk controller with data encryption function. Background technique [0002] Solid-state drive technology has brought unprecedented performance leaps in the field of hard drives. Data access performance that previously required a huge disk array can be achieved with a single solid-state drive, making it an ideal choice for high-performance storage devices. However, the cost of solid-state memory chips is still high at present, and its cost per GB is more than ten times that of traditional HDD hard disks. The high cost severely limits its application in consumer electronics such as notebooks and personal computers. In order to solve this contradiction, people combine traditional HDD with small-capacity solid-state hard disk to form a hybrid hard disk. Frequently accessed data is stored in solid-state hard disk to give full play to its performance advantages, while infrequent...
