Embodiment Construction

[0045] In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0046] Based on the above purpose, the first aspect of the embodiments of the present invention proposes an embodiment of a method for optimizing openblock in a solid state disk. figure 1 Shown is a schematic flow chart of the method.

[0047] like figure 1 As shown in , the method may include the following steps:

[0048] S1 detects whether the block in the solid-state disk is in the state of open block every preset time, and puts the detected block in the state of open block into the table.

[0049]When the block in the SSD is not full, after a certain period of time, the data in the last layer of the block will become unstable. This phenomenon is called the open block phenomenon. A timer can be set...

Abstract

The present invention provides a method, device, device and readable medium for optimizing an open block in a solid-state hard disk. The method includes: detecting whether the block in the solid-state hard disk is in the state of an open block every time a preset time passes, and converting the detected Put the block in the open block state into the table; monitor whether there are new records in the table in real time; respond to the monitoring of new records in the table, judge whether the block with the new record has an abnormal power-off mark; respond to the new record If the block has an abnormal power-off mark, use the content in the preset format to fill in the next layer of data of the block with the abnormal power-off mark to seal the block. By using the solution of the present invention, the problem of open block error correction can be effectively solved, while the impact on performance can be avoided, so that the performance of the solid-state hard disk is more stable.

Description

technical field [0001] This field relates to the computer field, and more specifically relates to a method, device, device and readable medium for optimizing open blocks in solid state disks. Background technique [0002] With the development and wide application of technologies such as the Internet, cloud computing, and the Internet of Things, in human life, massive data needs to be processed and stored all the time. The rapid development of information technology puts higher demands on the performance of storage systems. Require. Solid-state drives are widely used because of their fast read and write speeds and low energy consumption. However, due to the characteristics of NAND (solid-state hard drive), it is affected by the specific hardware electrical, that is, when the block (block) in NAND is not full, after a certain period of time, the last written layer (layer) of the block The data will become unstable, which is called the open block phenomenon, where there is a ...
