This invention provides a data storage device and a data reading method. The data storage device is coupled to a host computer, which includes a host memory buffer. The data storage device includes a controller, non-volatile memory, and a buffer. The data reading method includes: downloading firmware data to be updated from the data storage device via the host computer; determining that the host memory buffer contains the firmware data to be updated; reading the firmware data to be updated from the host memory buffer into the buffer; determining that the firmware data to be updated in the buffer is correct through an error correction mechanism; and updating the firmware data of the data storage device. This reduces read / write operations on the data storage device and improves stability, while also increasing data transmission speed without affecting read / write operations.

The application discloses a data processing method and device, equipment and a storage medium, relates to the technical field of data processing, and comprises the following steps: when receiving a data write request sent by a client, extracting to-be-written data information from the data write request; performing index calculation on the to-be-written data information according to a preset index rule to obtain first index information; matching the first index information with index information in a pre-constructed index table; and when the first index information matches second index information in the index table, performing a virtual copy operation on the to-be-written data. The method can reduce unnecessary read and write operations, thereby realizing fast data copying and effectively improving system performance. Meanwhile, the adoption of the virtual copy technology can reduce the occupation of actual storage space and avoid the waste of storage resources caused by repeated storage of the same data.
