Abstract

The invention discloses a storage equipment bad block processing method and device and storage equipment, and relates to the field of communication terminals. The problem that IOPS stability is poor in the storage equipment using process is solved. The storage equipment bad block processing method and device are applied to the storage equipment, and the storage equipment is provided with a user data area, an over-supply area and a reserved area. The user data area and the over-supply area are used for actually storing user data. The reserved area comprises a reserved block. When a bad block exists in the user data area, the type of the bad block is detected, a replacement reserved block is applied for replacing the bad block in the reserved area, and then the applied replacement reserved block replaces the bad block. According to the technical scheme, the storage equipment bad block processing method and device are applicable to the procedure in which the storage equipment processes the bad block.

Description

technical field [0001] The invention relates to the field of communication terminals, in particular to a method and device for processing bad blocks of a storage device and a storage device. Background technique [0002] With the development of network communication technology, the requirements for storage performance of storage devices are also getting higher and higher. For example, the storage performance of a storage device SSD (full name in English: Solid State Device / Solid State Drive, full name in Chinese: Solid State Drive) is determined by the IOPS (full name in English: Input / output Operations Per Second, full name in Chinese: The number of read and write operations per second) stability reflects that the more stable the IOPS, the better the storage performance of the SSD, that is, the better the user experience of using the SSD. The existing technology uses over-provisioning technology to improve the stability of IOPS in the life cycle of SSD. [0003] The over-...
