Storage management method, solid state hard disk and readable storage medium

Abstract

The invention provides a storage management method, a solid state hard disk and a readable storage medium. The method includes: when it is detected that the data imported by the storage channel needs to be stored, obtaining an available storage block, and writing the incoming data into the available storage block. When the data writing is completed, it is detected whether the status flag of the storage space is a non-overwrite status. When it is in the non-overwriting state, it is detected whether the storage space has reached the full state. When the storage space reaches the full state, the storage space status flag is switched to the copy state, and the timer is started, and the storage space recycling and allocation process is performed regularly according to the storage life coefficient of each storage block in the storage space and the life balance strategy of the storage block. As a result, the storage blocks in the storage space can be erased in a balanced manner, which improves the overall service life of the solid-state hard disk and improves the efficiency of data reading and writing.

Description

technical field [0001] The present invention relates to the technical field of storage, in particular to a storage management method, a solid-state hard disk and a readable storage medium. Background technique [0002] Solid State Drives (SSD, Solid State Drives) are hard disks made of solid-state electronic storage chip arrays, usually composed of a main control chip and a flash memory chip. The main control chip is the control unit responsible for controlling data storage in the solid state hard drive. A storage unit responsible for storing data in a solid-state drive. Among them, the core of the main control chip is FTL (FlashTranslationLayer, flash translation layer). FTL is responsible for address mapping, garbage collection, wear leveling, bad block management and other services. The quality of the FTL algorithm strategy determines the performance, efficiency, and life of the SSD. and stability. Flash memory is a long-life non-volatile (it can still maintain stored d...

AI Technical Summary

Problems solved by technology

When standard solid-state drives perform monitoring and storage services, the standard FTL architecture cannot meet the actual business storage requirements, and the storage performance is not superior enough

In addition, garbage collection and wear leveling will affect the read and write efficiency of solid state drives. When the storage space of solid state drives is close to full, garbage collection strategies and wear leveling algorithms with insufficient performance will not only fail to improve storage speed, but will limit the capacity of solid state drives. storage efficiency
