Embodiment Construction

[0037] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the application. Obviously, the described embodiment is only It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0038] The method for processing bad blocks of combined blocks provided in the embodiment of the present application is applied to solid-state hard disks. It is understandable that the solid-state hard disk includes multiple physical storage blocks. When the storage block can read and write data normally, it can be called a good block. When it cannot read and write...

Abstract

The invention discloses a method and device for processing bad blocks of combined blocks, which are applied to solid-state hard disks. The method includes: when there is a bad block for reading and writing in the first combined block, selecting a target good block from the storage blocks of the solid-state hard disk; There is data stored in a combination block, including one or more storage blocks in the solid-state hard disk; the target good block does not belong to the first combination block, and no data is stored in the target good block; if there is data stored in the read-write bad block, Then, the data stored in the read-write bad block is migrated to the target good block, which simplifies the processing flow, improves the processing efficiency, and saves storage space.

Description

technical field [0001] The present application relates to the technical field of data storage, in particular to a method and device for processing bad blocks of combined blocks. Background technique [0002] Storage block management is an important part of the solid state drive (Solid State Drives, SSD) firmware algorithm, in which the implementation method of the block and the management of the combination block are closely related to the read and write performance of the SSD. [0003] If the number of read-write bad blocks generated during the use of the combined block exceeds the preset value, it is generally necessary to move the data stored on the combined block to other free combined blocks, and to store data and combined blocks. The updating of the mapping table is cumbersome and inefficient. If the number of read / write bad blocks generated in the idle combination block exceeds a preset value during the data migration process, the processing flow will be more cumbers...
