SOLID-STATE DRIVE AND DATA PROCESSING METHOD AND SYSTEM THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/137152
Kind Code:
A1
Abstract:
A solid-state drive and a data processing method and system thereof. The method comprises: detecting an operation performed by a user on a first storage region of the solid-state drive, wherein the first storage region is visible to an operating system (S101); and if the operation is a read/write operation, maintaining data synchronization between the first storage region and a mirror data storage region of a second storage region on the solid-state drive, wherein the second storage region can be configured to be invisible to the operating system, or if the operation is a deletion operation or a TRIM operation, maintaining data synchronization between the first storage region and the mirror data storage region of the second storage region, and backing up data deleted from the first storage region to a deletion data storage region of the second storage region (S102). The second storage region of the method and system can be configured to be invisible to the operating system, so as to avoid a situation in which data is maliciously deleted or deleted data cannot be recovered due to a faulty operation. The use of a flash controller achieves data backup and recovery of the data on the solid-state drive.
