Abstract

The invention provides a data management method and device, a storage medium and an electronic device. The method comprises the steps that: state information of each physical block in the storage device is determined; under the condition that the physical blocks do not meet the target write-in mode, state information of the target physical blocks which do not meet the target write-in mode is stored in a first list, wherein the target write-in mode is used for indicating that the physical blocks support migration storage of multiple data; a migration list of the storage device is obtained, a virtual physical block bound to a target physical block on a corresponding migration node is determined according to the migration list, and information of the virtual physical block is stored in a second list, wherein the migration node is used for indicating the corresponding relation between the target physical block and the virtual physical block; and data writing management is performed on the storage device according to the migration list, the first list and the second list. The problem that the cost cannot be reduced while the reliability of the storage device is ensured in the prior art is solved.

Description

Technical field [0001] The present invention relates to the field of solid state drive technology, particularly, to a data management method and apparatus, a storage medium, the electronic apparatus. Background technique [0002] The rapid development of electronic products in the past few years technology, allowing consumers to experience higher and higher requirements for electronic products, the demand for higher speed and convenient storage products is increasing. Since the rewritable nonvolatile memory (rewritablenon-volatile memory) having a non-volatile, low power, small size, no mechanical structure, characteristics such as data read and write speed, the most suitable for portable electronic products such as notebook computers. SSD is a kind of flash memory as a storage medium storage device. Therefore, the flash memory industry in recent years, the electronics industry has become very popular in a ring. [0003] Storage mode currently on the market mainly two modes parti...
