Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] see image 3 , the present invention provides a weighted wear leveling system for solid state hard drives, the system 100 includes a recording module 10, a hash table generation module 20 and a calculation processing module 30, wherein:

[0040] The recording module 10 is used for recording bad blocks in the solid state disk. In specific applications, there may be many reasons for the bad blocks of the solid-state hard disk. For example, due to the error of the processing technology, bad blocks are generated when the factory leaves the factory; in addition, during the use of the solid-state...

Abstract

The invention is suitable for the technical field of computers, and provides a method for weighting wear balance of a solid state disk. The method comprises the steps as follows: recording at least one bad block of the solid state disk and a block number around the bad block; generating a hash table according to the block number around the bad block; and when the solid state disk is subjected to wear balance, weighting a wear balance coefficient of the block in the hash table. Correspondingly, the invention further provides a wear balance system for realizing the method. Therefore, the performance of the solid state disk can be improved and the service life of the solid state disk can be prolonged.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a weighted wear leveling method and system for a solid state disk. Background technique [0002] Solid State Disk (SSD for short) is a computer external storage device based on permanent memory, such as flash memory, or non-permanent memory, Synchronous Dynamic Random Access Memory (SDRAM). It has fast reading and writing speed, low power consumption, no noise, anti-vibration, low heat, small size, and large working range. It is widely used in military, vehicle, industrial control, video surveillance, network monitoring, network terminals, electric power, medical, aviation etc., navigation equipment and other fields. If it can overcome the low cost-effectiveness and life limitation, it will be more widely used. [0003] Since the storage medium flash of the solid-state hard disk has the characteristics of limited erasing times and erasing first, then writing, it will bring th...
