Problems solved by technology

However, there is currently no more effective priority technology for the TRIM command
[0005] To sum up, it can be seen that the existing delete command technology for optimizing solid-state hard drives is obviously inconvenient and defective in actual use, so it is necessary to improve

Embodiment Construction

[0039] 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.

[0040] see figure 1 , in the first embodiment of the present invention, a solid-state hard disk 100 is provided, including:

[0041] The trimming module 10 is configured to trim the deletion command when the deletion command of the solid state disk 100 is issued;

[0042] The issuing module 20 is configured to issue the trimmed deletion command when the preset condition is reached.

[0043] In this embodiment, the trimming module 10 first trims the pruning commands of the solid state disk 100 that need to be delivered, specifically including aligning, splitting, or aggregating the pruning command...

Abstract

The invention provides a method for optimizing a deletion command of a solid state disk and the solid state disk using the method. The method and the solid state disk are applicable to the storage technical field. The method includes the steps of modifying the deletion command when the deletion command of the solid state disk is issued, and issuing the modified deletion command after preparatory conditions are met. Therefore, the write amplification of the solid state disk is reduced, and the service life of the solid state disk is prolonged.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a method for optimizing a pruning command of a solid-state hard disk and the solid-state hard disk. Background technique [0002] SSD (Solid State Disk, solid state drive) is a computer external storage device based on permanent memory, such as flash memory, or non-permanent memory, SDRAM (Synchronous Dynamic Random Access Memory, Synchronous Dynamic Random Access Memory). 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] When a file is deleted, the operating system does not actually delete the d...
