[0084] Based on the above hardware structure, an embodiment of the SSD performance degradation recovery method of the present invention is proposed.

[0085] Reference Figure 2 , Figure 2 FIG. 4 is a flow chart of a first embodiment of a method for recovering from SSD performance degradation according to the present invention.

[0086] In a first embodiment, the SSD performance degradation recovery method comprises the following steps:

[0087] Step S10: When receiving the SSD performance recovery instruction, the standard command of the SSD device is expanded to obtain a specific instruction.

[0088] It should be noted that the SSD performance recovery instruction is an instruction for performing performance recovery on the SSD device. When the SSD performance recovery instruction is received, the standard command of the SSD device is extended to obtain a specific instruction, and the specific instruction is an instruction for performing SSD performance recovery on the SSD device.

[0089] Step S20: establishing communication between the SSD device and the platform, executing the specific instruction, and obtaining a recovery result after the specific instruction is completed.

[0090] It should be understood that after the communication between the SSD device and the platform is established, the specific instruction can be executed, and after the specific instruction is completed, the corresponding SSD recovery result is obtained.

[0091] Step S30: after the recovery result meets the requirements, reuse the SSD device.

[0092] It is understandable that after the recovery result meets the requirements, the SSD device can be reused, that is, after the read and write performance of the SSD is restored, the SSD device can be reused.

[0093] Through the above scheme, this embodiment obtains specific instructions by extending the standard commands of the SSD device when receiving the SSD performance recovery instruction; establishes communication between the SSD device and the platform, executes the specific instructions, and obtains the recovery result after the specific instructions are completed; after the recovery result meets the requirements, the SSD device is reused, which can have better system compatibility, so that the read and write performance of the SSD is basically restored to its original state, thereby improving the speed and efficiency of SSD performance recovery and improving user experience.

[0094] Further, Figure 3 FIG. 2 is a flow chart of a second embodiment of a method for recovering from SSD performance degradation according to the present invention. Figure 3 As shown, a second embodiment of the SSD performance degradation recovery method of the present invention is proposed based on the first embodiment. In this embodiment, step S10 specifically includes the following steps:

[0095] Step S11: upon receiving the SSD performance recovery instruction, authenticating the SSD device.

[0096] It should be noted that when the SSD performance recovery instruction is received, the SSD device can be authenticated.

[0097] Step S12: When the SSD device passes authentication, the standard command of the SSD device is expanded to obtain a specific instruction.

[0098] It is understandable that when the SSD device passes the authentication, the standard command of the SSD device can be expanded to obtain the corresponding specific instruction.

[0099] Furthermore, before step S12, the SSD performance degradation recovery method further includes the following steps:

[0100] When the SSD device can perform a refresh operation, determining that the SSD device authentication is passed;

[0101] When the SSD device cannot perform the Refresh operation, it is determined that the SSD device authentication fails.

[0102] It can be understood that when the SSD device can perform the Refresh operation, it can be determined that the SSD device authentication has been passed, and when the SSD device cannot perform the Refresh operation, it can be determined that the SSD device authentication has not been passed.

[0103] In a specific implementation, an SSD device is selected and SSD device authentication is performed to check whether a refresh operation can be performed. If the device does not support the refresh operation, a prompt is given that the device does not support the refresh operation and the process ends. If the device supports the refresh operation, it can be determined that the SSD device authentication has passed.

[0104] Through the above scheme, this embodiment authenticates the SSD device when receiving the SSD performance recovery instruction; when the SSD device passes the authentication, the standard command of the SSD device is expanded to obtain specific instructions, and the specific instructions can be obtained quickly, thereby improving the speed and efficiency of SSD performance recovery.

[0105] Further, Figure 4 FIG. 4 is a flow chart of a third embodiment of a method for recovering from SSD performance degradation according to the present invention. Figure 4 As shown, a third embodiment of the SSD performance degradation recovery method of the present invention is proposed based on the second embodiment. In this embodiment, the step S11 specifically includes the following steps:

[0106] Step S111: upon receiving an SSD performance recovery instruction, turning on the SSD device.

[0107] It should be noted that when the SSD performance recovery instruction is received, the software can be opened, the SSD device can be found, and then the SSD device can be turned on.

[0108] Step S112: Enable the authentication function to determine whether the SSD device can perform a refresh operation.

[0109] It is understandable that after the authentication function for the SSD device is enabled, it can be determined whether the SSD device can perform a refresh operation.

[0110] Through the above scheme, this embodiment turns on the SSD device when receiving the SSD performance recovery instruction; turns on the authentication function to determine whether the SSD device can perform a refresh operation, and can make a preliminary judgment before the recovery operation, thereby improving the speed and efficiency of SSD performance recovery and improving the user experience.

[0111] Further, Figure 5 FIG. 4 is a flow chart of a fourth embodiment of a method for recovering from SSD performance degradation according to the present invention. Figure 5 As shown, a fourth embodiment of the SSD performance degradation recovery method of the present invention is proposed based on the second embodiment. In this embodiment, step S12 specifically includes the following steps:

[0112] Step S121: When the SSD device passes authentication, obtain a standard command of the SSD device.

[0113] It should be noted that, when the SSD device passes the authentication, the standard command of the SSD device can be obtained.

[0114] Step S122: Extend the standard command using the LID of DWORD 10 and the lower 8 bits of NUMD to obtain a specific instruction.

[0115] In a specific implementation, the Refresh instruction may be extended by using the LID of DWORD 10 and the lower 8 bits (23:16) of NUMD, thereby obtaining the extended instruction, ie, the specific instruction.

[0116] Through the above scheme, this embodiment obtains the standard command of the SSD device when the SSD device is authenticated; the standard command is extended by using the LID of DWORD 10 and the lower 8 bits of NUMD to obtain specific instructions; the specific instructions can be obtained quickly, thereby improving the speed and efficiency of SSD performance recovery.

[0117] Further, Figure 6FIG. 5 is a flow chart of a fifth embodiment of a method for recovering from SSD performance degradation according to the present invention. Figure 6 As shown, a fifth embodiment of the SSD performance degradation recovery method of the present invention is proposed based on the first embodiment. In this embodiment, step S20 specifically includes the following steps:

[0118] Step S21: establishing communication between the SSD device and the platform, and reminding the user whether to perform a recovery operation.

[0119] It should be noted that after the communication between the SSD device and the platform is established, the user can be reminded whether to perform a recovery operation.

[0120] Step S22: When the confirmation recovery operation instruction is received, the specific instruction is executed, the Refresh operation status function is called, and the user is informed of the progress of the current Refresh operation until the Refresh operation is completed.

[0121] It is understandable that, when the confirmation recovery operation instruction is received, the specific instruction can be executed, the Refresh operation status function can be called, and the user can be informed of the progress of the current Refresh operation until the Refresh operation is completed.

[0122] In the specific implementation, if the device supports the Refresh operation, the user is prompted whether to confirm the Refresh operation; if the user selects Cancel, the process ends; if the user selects Confirm, the Refresh operation is performed, and the function for obtaining the Refresh operation status is called. At the same time, the user can be informed of the progress of the current Refresh operation.

[0123] Step S23: After the specific instruction is completed, a recovery result is obtained.

[0124] It should be understood that after the specific instruction is completed, the corresponding recovery result can be obtained.

[0125] Through the above scheme, this embodiment establishes communication between the SSD device and the platform to remind the user whether to perform a recovery operation; when receiving the confirmation recovery operation instruction, executes the specific instruction, calls the Refresh operation status function, and informs the user of the progress of the current Refresh operation until the Refresh operation is completed; after the specific instruction is completed, the recovery result is obtained; better system compatibility can be achieved, so that the read and write performance of the SSD is basically restored to its original state, and the speed and efficiency of SSD performance recovery are improved.

[0126] Further, Figure 7 FIG. 6 is a flow chart of a sixth embodiment of a method for recovering from SSD performance degradation according to the present invention. Figure 7As shown, a sixth embodiment of the SSD performance degradation recovery method of the present invention is proposed based on the first embodiment. In this embodiment, step S30 specifically includes the following steps:

[0127] Step S31, determining whether the recovery result meets preset requirements.

[0128] It should be noted that, when judging whether the recovery result meets the preset requirement, the preset requirement is a preset requirement for judging whether the recovery result meets the standard, that is, whether the read and write performance of the SSD meets the preset requirement.

[0129] Step S32: When the recovery result meets the preset requirement, a recovery completion message is sent to the user.

[0130] It is understandable that when the recovery result meets the preset requirement, the recovery completion information can be sent to the user in a timely manner.

[0131] Step S33, executing the Sanitize command, and reusing the SSD device when the Sanitize command is completed and a restart instruction from the user is received.

[0132] It should be understood that when the Sanitize command is executed, after the Sanitize command is completed and the user's restart instruction is received, the SSD device can be reused. After receiving the specific instruction, the SSD executes the Sanitize command, and after waiting for the command to be completed, the user reuses the SSD, and the read and write performance of the SSD is basically restored to normal.

[0133] In the specific implementation, during the sanitization process, the system's standard commands sanitize and IO will be SSDabort, and the sign of the end of sanitization is status returns success.

[0134] Through the above scheme, this embodiment determines whether the recovery result meets the preset requirements; when the recovery result meets the preset requirements, sends recovery completion information to the user; executes the Sanitize command, and when the Sanitize command is completed and the user's restart instruction is received, reuses the SSD device; can have better system compatibility, so that the read and write performance of the SSD is basically restored to its original state, improves the speed and efficiency of SSD performance recovery, and improves user experience.

[0135] Accordingly, the present invention further provides an SSD performance degradation recovery device.

[0136] Reference Figure 8 , Figure 8 This is a functional module diagram of the first embodiment of the SSD performance degradation recovery device of the present invention.

[0137] In a first embodiment of the SSD performance degradation recovery device of the present invention, the SSD performance degradation recovery device comprises:

[0138] The extension module 10 is used to extend the standard command of the SSD device to obtain a specific instruction when receiving an SSD performance recovery instruction.

[0139] The recovery module 20 is used to establish communication between the SSD device and the platform, execute the specific instruction, and obtain the recovery result after the specific instruction is completed.

[0140] The reuse module 30 is used to reuse the SSD device after the recovery result meets the requirements.

[0141] The expansion module 10 is also used to authenticate the SSD device when receiving an SSD performance recovery instruction; when the SSD device passes the authentication, the standard command of the SSD device is expanded to obtain a specific instruction.

[0142] The expansion module 10 is further used to start the SSD device when receiving an SSD performance recovery instruction; start the authentication function to determine whether the SSD device can perform a refresh operation.

[0143] The expansion module 10 is further used to determine that the SSD device authentication is passed when the SSD device can perform the Refresh operation; and to determine that the SSD device authentication is failed when the SSD device cannot perform the Refresh operation.

[0144] The expansion module 10 is further used to obtain the standard command of the SSD device when the SSD device is authenticated; and to expand the standard command using the LID of the DWORD 10 and the lower 8 bits of the NUMD to obtain a specific instruction.
