Abstract

The embodiment of the invention provides a consumption balance processing method and a system as well as a solid hard disk. The method comprises the following steps that: a data on logical block number (LBN) corresponding to a first concurrency passage is moved to the LBN corresponding to a second concurrency passage, in addition, the data on the LBN corresponding to the second concurrency passage is moved to the LBN corresponding to a third concurrency passage, and in the same manner, the data on the LBN corresponding to a final concurrency passage is moved onto the LBN corresponding to the first concurrency passage. The embodiment of the invention can realize the full disk balance.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of storage, and in particular, to a wear leveling processing method and system, and a solid-state hard disk. Background technique [0002] A solid state disk (Solid State Disk, hereinafter referred to as SSD) is widely used due to its outstanding IO capability. In order to meet high performance requirements, SSDs generally adopt a multi-concurrency architecture, that is, the data path sends data at the same time according to the Flash particles used. Due to the limited erasable times of Flash particles, and some hot data on some Flash particles are frequently erased and written, and some non-hot data on some Flash particles are not erased and written for a long time, resulting in unbalanced wear and tear of Flash particles, which affects the performance of SSDs. service life. [0003] In order to balance the loss of Flash particles, the static balance adopted in the prior art is to fo...
