Abstract

The invention discloses a processing method, device and storage device for bad blocks of a storage device, relates to the field of communication terminals, and is used to solve the problem of poor IOPS stability during the use of the storage device. The specific embodiments provided by the present invention are applied to a storage device, and the storage device is configured with: a user data area, an over-provision area, and a reserved area, wherein the user data area and the over-provision area are used to actually store user data, and the reserved area includes a reserved area Reserve blocks; when there is a bad block in the user data area, detect the type of the bad block, and apply for a replacement reserved block in the reserved area for the bad block, and then replace the reserved block with the applied replacement reserved block according to the type of bad block bad block. The technical solution provided by the invention is applicable to the processing flow of the storage device for bad blocks.

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-...
