Embodiment 1

[0059] The method for estimating the remaining life time of the SSD disk provided in Embodiment 1 effectively estimates the remaining life time of the SSD disk and avoids data loss. Considering that there are differences in the decay rate of the remaining life value of the SSD disk in different trial stages, for example, the decay rate of the remaining life percentage of the SSD disk from 100% to 90% is obviously lower than the decay rate from 20% to 10%, so the present invention Embodiment 2 of a method for estimating the remaining life time of an SSD is also provided.

Embodiment 2

[0060] The second embodiment of the method for estimating the remaining life time of the SSD disk provided by the present invention will be described in detail below, as figure 2 , embodiment two specifically includes:

[0061] Step S21: Obtain the current remaining life percentage of the SSD disk every preset time.

[0062] Step S22: Obtain the time difference between the time when the remaining life percentage of the preset number of SSD disks is reduced by the preset life time percentage, and the time difference is between the time when the time difference is generated and the current time. The time difference value of the preset number of conditions.

[0063] Wherein, the preset number may be 10, the preset percentage may be 1%, and the preset condition may be all of the preset numbers that are closest between the generation time and the current time. time difference.

[0064] Specifically, the time difference can be stored in a dynamic array L_array[n], the dynamic ar...

Abstract

The invention discloses a method for estimating the remaining life of an SSD. The method realizes effective use of the current remaining life of an SSD and comprises acquiring the current remaining life of an SSD and a time difference of reduction of remaining lives of multiple SSDs by a preset life value, and calculating the remaining life of the SSD according to the current remaining life, the remaining life and the time difference so that the remaining life of the SSD is estimated and a data loss is effectively avoided. The invention also provides a device, equipment and computer-readable storage medium for estimating the remaining life of an SSD.

Description

technical field [0001] The present invention relates to the field of storage, in particular to a method, device, equipment and a computer-readable storage medium for estimating the remaining life time of an SSD disk. Background technique [0002] With the development of science and technology, information surges, and people need to store a large amount of data in order to read and write data. A common device used to store data is a hard disk. Among them, a solid-state disk SSD is a permanent memory or a non-permanent memory such as a synchronous dynamic random access memory computer external storage device. Compared with traditional hard disks, the performance is much better. Widely recognized by users. [0003] However, since the SSD disk uses the FLASH chip as the storage medium, its storage unit has a special structure, so it has a certain limit on the number of reads and writes. That is to say, the lifespan of the SSD disk is short. If the user cannot know the remainin...
