Embodiment 1

[0031] Embodiment one, such as figure 1 As shown, the embodiment of the present invention provides a method for early warning of the life of a solid-state hard disk, which may include:

[0032] Step 101: monitoring the life state of the solid state drive;

[0033] The above-mentioned monitoring of the life state of the solid-state hard disk can be: counting the erase / write operations of the above-mentioned solid-state hard disk; of course, it is also possible to use other methods to monitor the life state of the hard disk, such as monitoring the health status of the above-mentioned solid-state hard disk; it can be understood that the specific Which monitoring method does not affect the realization of the embodiment of the present invention should not be interpreted as a limitation of the embodiment of the present invention;

[0034] Step 102: judging whether the above life state reaches the set early warning value;

[0035] The above-mentioned judging whether the life state ...

Embodiment 2

[0043] Embodiment two, such as figure 2 As shown, the embodiment of the present invention also provides an alarm device applied to solid-state hard drives, which may include:

[0044] A monitoring unit 201, configured to monitor the life state of the solid-state hard disk;

[0045] A judging unit 202, configured to judge whether the above-mentioned life state reaches a set early warning value;

[0046] The alarm unit 203 is configured to issue an early warning signal when the life state reaches a set early warning value.

[0047] Such as image 3 As shown, the above-mentioned monitoring unit 201 may include:

[0048] A counting unit 301, configured to monitor the number of erasing / writing operations of the solid-state hard disk and / or the number of remaining reserved blocks of the solid-state hard disk;

[0049] The judging unit 202 is configured to judge whether the number of times of erasing / writing operations and / or the number of remaining reserved blocks reaches a set...

Embodiment 3

[0056] Embodiment three, such as Figure 5 As shown, the embodiment of the present invention also provides a solid state hard disk, which may include:

[0057] The controller 501 is used to detect and monitor the life state of the solid-state hard disk, and judge whether the above life state reaches the set early warning value;

[0058] The alarm 502 sends out an early warning signal when the life state reaches the set early warning value.

[0059] Such as Figure 6 As shown, the above-mentioned controller 501 includes:

[0060] The counter 601 is used to monitor the number of erasing / writing operations of the solid-state hard disk and / or the number of remaining reserved blocks of the solid-state hard disk;

[0061] A judging unit 602, configured to judge whether the number of erasing / writing operations and / or the number of remaining reserved blocks reaches a set warning value;

[0062] The above-mentioned alarm 502 is configured to issue an early warning signal when the n...

Abstract

The embodiment of the invention discloses an early warning method for the life service of a solid state disc, an alarm device, the solid state disc and an early warning system. The early warning method for the life service may comprises the following steps of: monitoring the service life state of the solid state disc; judging whether the service life state reaches a set early warning value or not; and sending an early warning signal when the service life state reaches the set early warning value. The technical scheme has the advantages that: by monitoring the service life state of the solid state disc, the early warning for the service life is carried out when the service life state approaches the set early warning value; and a prompt is given before data are possibly lost, so a user can prepare a data backup in advance, and the reliability of the solid state disc and the safety of the data stored in the solid state disc are improved.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a method for early warning of life of a solid-state hard disk, a solid-state hard disk and an early warning system. Background technique [0002] The storage unit of the Solid State Disk (SSD) uses a non-volatile flash memory (Flash) chip, and the SSD no longer uses a mechanical rotating device, so the SSD has higher read and write performance, stronger shock resistance, and lower power consumption. Smaller and other advantages. It can be used in military, vehicle, industrial control, video surveillance, network surveillance, network terminals, electric power, medical, aviation, navigation equipment and other fields. The structure of FlashSSD generally adopts single-level storage (Single Level Cell, SLC) and multi-level storage (Multi Level Cell, MLC). Among them, SSD erase / write life is limited, for example: the erase / write of SSD with SLC structure The lifespan is about 100,...
