Life prediction method and device for solid state disk and computer readable storage medium

Abstract

The invention discloses a solid state disk life prediction method and device and a computer readable storage medium. The method comprises that the daily user system write-in amount of a to-be-tested solid state disk in a preset historical time period is acquired, and a differential historical time sequence used for representing the daily change condition of the user system write-in amount of the to-be-tested solid state disk in the preset historical time period is generated; the differential historical time sequence is input into a pre-trained exponential smoothing model to obtain a daily variation prediction value of the user system write-in quantity of the to-be-tested solid state disk in a preset future time period; the service life of the to-be-tested solid state disk is predicted according to the actual user system write-in quantity of the day before the prediction day, the daily variation prediction value and the total write-in data of the to-be-tested solid state disk; and the weights given to the write-in change values at different times are different, so that the predicted value can accurately reflect the change condition of recent data write-in, and the prediction accuracy of the SSD life is effectively improved.

Description

technical field [0001] The present application relates to the technical field of life detection of solid-state hard disks, and in particular to a life prediction method, device and computer-readable storage medium of solid-state hard disks. Background technique [0002] SSD (Solid-state disk, solid-state disk) is a hard disk made of solid-state electronic memory chip array, which consists of a control unit and a storage unit such as a FLASH chip or a DRAM chip. Because SSD has the advantages of fast reading and writing, light weight, low energy consumption and small size, it replaces traditional HDD (Hard Disk Drive, mechanical hard disk) and is widely used in military, vehicle, industrial control, video surveillance, network monitoring, network terminals, Electricity, medical treatment, aviation, navigation equipment and many other fields. [0003] As a high-performance alternative to HDDs, flash-based SSDs have been widely sought after since their inception. And with the...

AI Technical Summary

Problems solved by technology

[0007] It can be seen from the fixed life calculation formula that related technologies use all past data equally when predicting SSD life, that is, the daily changes in the past are treated equally. In actual SSD use, the user's future The amount of writing is likely to be similar to that in the near future, so it is impossible to accurately predict the SSD life by using all historical data equally
