Description
Technical field
The present invention relates to SSD label information Examined effect field, more specifically refer to a kind of test SSD label information
Method and device thereof.
Background technique
The label information of SSD has very much, such as sequence number, model etc..These information are extremely important, if the mark of mistake
The sample of label information is sent to ODM factory or client on hand, then will cause very big trouble.
It is all the letter that inspection tag and CDI tool are shown one by one by hand in the technology of existing test SSD label information
Whether breath is consistent, and along with the information of label is very more, this just seems quite time-consuming laborious；And it is more in the quantity of SSD
In the case of, the cooperation of more people is generally required, heavy workload, time and effort consuming, human cost is higher, and testing efficiency is low, can not
Meet demand.
Summary of the invention
It is an object of the invention to overcome the deficiencies of existing technologies, provide it is a kind of test SSD label information method and its
Device.
To achieve the above object, the invention adopts the following technical scheme:
A method of test SSD label information, comprising the following steps:
Build test environment；
Defined variable, and setting script running environment；

It compares；If result is consistent, labeled as qualification；If inconsistent, labeled as unqualified.
Its further technical solution are as follows: the step of described " build test environment " includes: by host desktop and keyboard, mouse
Mark and display connection, the mainboard and PSPA of the host desktop, M.2 pinboard and SSD to be measured are electrically connected, operation
Driver Master software executes test script.
Its further technical solution are as follows: the variable in " defined variable, and the setting script running environment " step includes
Test errors, host LBA write-in, SLC LBA write-in, LCRC mistake and caution sign.
Its further technical solution are as follows: described " to be showed the log page information of SSD column come and by day by cyclical function
Will page information is compared one by one with SSD label " the step of include:
Read the information of SSD log page；
Carry out the inspection of SSD model；
Carry out the inspection of SSD sequence number；
Carry out the inspection of SSD 8S bar code；
Check LEN identifier；
It is writeable to check whether SSD main flash and SLC buffer are supported.
Its further technical solution are as follows: described " to be showed the log page information of SSD column come and by day by cyclical function
Will page information and SSD label are compared one by one " the log page information of SSD in step arrange show the following steps are included:
Host sends the order for reading log page to reada buffer；
Judge to read whether log page succeeds；If unsuccessful, test errors are assigned a value of 1, and print and cannot successfully read
Take log page；
Print the value of identifier；
Print the value of model number；
Print the value of sequence number；
Print the value of 8S bar code.
Its further technical solution are as follows: the step of inspection of SSD model " carry out " includes: to judge SSD model and institute
Whether the value for stating printing model number is consistent；If so, printing SSD model checks correctly；It is checked not if it is not, then printing SSD model
Correctly；The step of " inspection of SSD sequence number " include: judge SSD sequence number and it is described printing sequence number value whether one
It causes；If so, printing SSD sequence number checks correctly；If it is not, it is incorrect then to print the inspection of SSD sequence number.
Its further technical solution are as follows: the step of " inspection of SSD 8S bar code " includes: to judge SSD 8S bar shaped
Whether code is consistent with the value of the printing 8S bar code；If so, printing SSD 8S bar code checks correctly；If it is not, then printing SSD
8S bar code checks incorrect；The step of described " checking LEN identifier " includes: to judge that LEN identifier and the printing identify
Whether the value of symbol is consistent；If so, printing LEN identifier checks correctly；If it is not, it is incorrect then to print the inspection of LEN identifier.
Its further technical solution are as follows: the step of described " it is writeable to check whether SSD main flash and SLC buffer are supported " wraps
It includes:
It is writeable to judge whether SSD main flash is supported；If so, printing SSD main flash support is write；If it is not, then printing the main sudden strain of a muscle of SSD
It deposits and does not support to write；
It is writeable to judge whether SLC buffer is supported；If so, printing SLC buffer support is write；If it is not, then printing SLC buffering
Device is not supported to write.
