The present disclosure discloses a method, a system, and a solid-state drive for data processing. The method includes detecting the user operations on a first storage area which is visible to an operating system in a solid-state drive; if the user operation is a reading or writing operation, keeping the data of the first storage area and the data of a mirrored data storage area of a second storage area to be synchronization; if the user operation is a deleting operation or a TRIM operation, keeping the data of the first storage area and the data of the mirrored data storage area of the second storage area to be synchronization, and backing up the deleted data from the first storage area to a deleted data storage area of the second storage area. The second storage area is set to be invisible to the operating system in the solid-state disk.
A method for data processing in a solid-state drive comprising a first storage area and a second storage area, the second storage area comprising a mirrored data storage area for mirroring data stored in the first storage area and a deleted data storage area for storing data deleted from the first storage area, the first storage area being visible to an operating system and the second storage area being set to invisible to the operating system, the method comprising:
A solid-state drive, comprising:
