Further, as a kind of embodiment.Before described step S100, also comprise step R100:
Step R100, gather different model, corresponding normal data the Criterion database of four test points of the solid state hard disc of different size in advance.
In above-mentioned steps R100, gather in advance different model, the object of the normal data that four test points of the solid state hard disc of different size are corresponding is to provide data basis for Criterion database.Normal data is used for follow-up contrastive detection data provides reference information.
Preferably, in above-mentioned steps S100, above-mentioned object information comprises the firmware version number (Firmware) of product type (ModelNumber) and each solid state hard disc of the quantity of a plurality of solid state hard discs, the product ID of each solid state hard disc (SN), each solid state hard disc; Wherein, for example: in object information the product ID of solid state hard disc (SN) at product after user uses and occur to damage, the relevant information that the test of dispatching from the factory being provided when retesting monitoring solid state hard disc is as with reference to according to using to detect.The version of software when the firmware version number of solid state hard disc (Firmware) bakes part for locating to SSD.Its object is mainly used in firmware upgrade, and new firmware is write in chip, replaces original firmware.
Preferably, as a kind of embodiment.In above-mentioned steps S200, carry out the instruction of the configuration parameter information that receives user configured current solid state hard disc, above-mentioned configuration parameter information comprises following information: the size of the data block that writes/read, the test No. of each solid state hard disc, be sent to the quantity of the order of solid state hard disc at every turn, the selection instruction of test point type, the duration of the test duration of each solid state hard disc and test displaying time point.
Above-mentioned configuration parameter information can be presented on human-computer interaction interface by said apparatus corresponding module, and user adds above-mentioned configuration parameter information according to the testing requirement of solid state hard disc.Every solid state hard disc needs to test four points altogether, and { (order writes, Sequential Write), (order reads, Sequential Read), (random writing, Random Write), (read at random, Random Read) }, each point will carry out test job through above-mentioned 4 test points.Before solid state hard disc test, need user to be configured above-mentioned parameter information.
The parameter that the order of take below in modification configuration parameter information writes (Sequential Write) is example:
sd=sd1,lun=\\.\physicaldrive=0,threads=32;
wd=wd1,sd=sd*,seekpct=seq,rdpct=0,xfersize=256K;
rd=rd1,wd=wd*,elapsed=18,interval=1,iorate=max;
It should be noted that, in above-mentioned speech encoding, 0 test No. (representing the test No. of different solid state hard discs by numeral number) that represents solid state hard disc in physicaldrive=0; In threads=32 32 representative is sent to the quantity of the order of solid state hard disc at every turn, and while adopting multi-threading, each solid state hard disc of carrying out is carried out a plurality of orders, and in this example, 32 representatives adopt multi-threading to be sent to the quantity of the order of solid state hard disc at every turn; The quantity (queue depth) that is at every turn sent to the order of solid state hard disc by configuration modification improves I/O performance.Its essence is that the mode that sends again solid state hard disc by order is placed in queue to can improve I/O performance.
In rdpct=0,0 representative writes (Write) instruction, and read accordingly (Read) instruction, is 100, and the 256K in xfersize=256K is the size of predetermined test data piece;
18 total testing times that represent solid state hard disc in elapsed=18, in interval=1,1 representative shows the Monitoring Data (testing the duration of displaying time point) of every 1 second (s); Above-mentioned configuration parameter information is not repeating one by one.
Above configuration parameter information only needs to click corresponding button input configuration parameter information on the human-computer interaction interface of user's said apparatus corresponding module just can realize the modification of configuration parameter information.
Revise " seq " in " seekpct=seq "
Revise " 256K " in " xfersize=256K "
Revise " 18 " in " elapsed=18 "
When the performance test methods of the solid state hard disc that the embodiment of the present invention provides is specifically implemented, can receive user's configuration parameter information command and reach by adopting multi-threading to carry out corresponding instruction the object that realizes test solid state hard disc performance.
Further, as a kind of embodiment.Described step S300 specifically comprises the steps, as shown in Figure 2:
In above-mentioned steps S300, receive after configuration-direct, adopt multi-threading simultaneously to a plurality of solid state hard discs sequentially write, order reads, random writing, read these four test points at random and test; That realizes multi-threading take multithreading as support.About multithreading, be that CPU can carry out multiple thread simultaneously, just can allow CPU bring into play larger efficiency, also claim " hyperthread (Hyper-Threading is called for short " HT ") " technology.Hyper-Threading is exactly to utilize special hardware instruction, two logic kernels are modeled to two phy chips, allow single processor can use Thread-Level Parallelism to calculate, and then compatible multithreading operation system and software, reduced the standby time of CPU, the operational efficiency of the CPU of raising.
Adopt hyperthread be can be at one time in, application program can be used the different piece of chip.Although single-threaded chip can be processed thousands of instructions p.s., is merely able at any one time an instruction to operate.And Hyper-Threading can make chip carry out multithreading processing simultaneously, chip performance is got a promotion.
Step S310, when each test point of current solid state hard disc is tested, first wipe the storage data in current solid state hard disc, and according to the configuration parameter information of current solid state hard disc, each test point tested;
When each test point test, first wipe, then test.Carrying out auto-erasing (TRIM) instruction allows operating system can notify which data block of solid-state drive can not re-use; Otherwise solid-state hard disk controller does not know to reclaim these idle data blocks, TRIM just sends to solid state hard disc the operation that empties block, make solid state hard disc know that this content deleted, this place just can be counted as blank, when writing balance, just can carry out balance in these whole places like this, while carrying out write operation so again, just can not occur the problem of hydraulic performance decline again.TRIM will greatly reduce and write burden, allow that SSD is pre-on backstage better deletes idle data block simultaneously, to allow these data blocks can prepare quickly new writing.Large feature of TRIM is exactly: reclaim idle solid state hard disc data block.After erase operation finishes, first carry out the dependent instruction of call configuration option information and carry out the test operation of corresponding test point in configuration parameter information.At said sequence, write in (Sequential Write) example, understood in detail configuration parameter information and performed instruction.
Step S320, after described four test points of current solid state hard disc have all been tested, draw corresponding continuous time point Monitoring Data simultaneously generate SMART information, the Monitoring Data of the continuous time point of the described current solid state hard disc of test record is kept in the file of html format and the SMART information of generation is kept in text.
In above-mentioned steps S320, relate generally to and record SMART information, and draw the steps such as Monitoring Data.Illustrate: by carrying out corresponding test instruction, the Monitoring Data (logfile.html) of continuous time point of the described current solid state hard disc of test record will be obtained, meanwhile also generated SMART information, the Monitoring Data of the continuous time point of the described current solid state hard disc of test record has been kept in the file of html format and SMART information is kept in text; Information (SMART, Self-Monitoring, Analysis, and Reporting Technology) that SMART information is " self-monitoring, analyze and reporting techniques ", SMART information can be used for the potential problems of forecast analysis hard disk.
Above-mentioned SMART information mainly includes the information such as sequence number, residual life and bad piece number of solid state hard disc, and SMART information is mainly used in after completing test, checks the abrasion condition of solid state hard disc, and estimates the life-span of solid state hard disc under specific environment.
Preferably, because while testing each test point, all according to the duration of the test displaying time point in configuration parameter information, carry out the test of corresponding test point, so Monitoring Data will be the performance data that one group of group records each time point, by above-mentioned Monitoring Data, can provide the test report that portion has time point, if current solid state hard disc occurs abnormal, can find accurately abnormal time point by test report, and provide accordingly the abnormal error report of detailed time point.Provide the report of abnormal time point and will meet to a great extent high-quality test request.
Further, as a kind of embodiment.Described step S400 specifically comprises the steps:
Step 410, utilize EXCEL VBA method of operating the Monitoring Data in the file of described html format imported in the file of form of EXCEL and filter the Monitoring Data that there is no reference value, retain valuable Monitoring Data and according to the Monitoring Data after filtering, calculate minimum value and the mean value of I/O read-write frequency and the transfer rate of each test point.
First, the Monitoring Data of testing (logfile.html) is processed, utilize EXCEL VBA method of operating to call in the text of form that dependent instruction and function import to the Monitoring Data in the file of described html format EXCEL, filter the Monitoring Data that there is no reference value, retain valuable Monitoring Data and calculate the I/O read-write frequency of each test point and the minimum value of transfer rate (min value) and mean value (Avg value) according to the Monitoring Data after filtering.Certainly in logfile.html Monitoring Data, contain the information that there is no in a large number reference value, filtering data remains the Monitoring Data with reference value and is that follow-up solid state hard disc performance evaluating is prepared.Wherein, when execution calculates the I/O read-write frequency of each test point and the minimum value of transfer rate and mean value operation, utilize VBA to process statement and process above-mentioned text, obtain min value and the Avg value of I/O read-write frequency and transfer rate.
Wherein, I/O read-write frequency (IOPS, Input/Output Operations Per Second), i.e. the number of times of per second read-write (I/O) operation, reflects the data throughout (being the number of times that carries out input/output operations per second) of solid state hard disc and for weighing the performance of random access.The IOPS performance of storage end and the IO of host side are different, and IOPS refers to that SSD is per second and accept the access that how many times main frame sends, and an IO of main frame need to repeatedly access storage and just can complete.For example, main frame writes a minimum data block, also will be through three steps such as " send write request, data writing, receive write confirmations ", and namely 3 storage ends are accessed.
The implication of the unit of transfer rate (MB/s) is megabyte per second, refers to the byte quantity of transmission per second, and the common practise that I/O read-write frequency and transfer rate are the art no longer describes in detail this.
Further, as a kind of embodiment.Described step S500 specifically comprises the steps:
Step S510, in standard database standard I/O read-write frequency of standard testing point and minimum value and the mean value of transfer rate of retrieval and the corresponding solid state hard disc of current solid state hard disc same model and specification;
Step S520, judge I/O read-write frequency and the minimum value of transfer rate and standard I/O read-write frequency of standard testing point and minimum value and the mean value of transfer rate whether mean value is all more than or equal to solid state hard disc corresponding in corresponding standard database that each test point of described current solid state hard disc is corresponding;
Step S530, if the determination result is YES, judges that the performance test results of the current solid state hard disc of testing is as qualified; If the determination result is NO, judge that the performance test results of the current solid state hard disc of testing is as defective.
It will be understood by those skilled in the art that in above-mentioned steps S510 ~ step S530, preferably, judge I/O read-write frequency that each test point of described current solid state hard disc is corresponding and minimum value and the mean value of transfer rate; And contrast the normal data of the test point in respective standard database.Like this with the Monitoring Data through test and normal data contrast reference, can assess the performance of current solid state hard disc, standard I/O read-write frequency by the corresponding test point with standard database and standard transmission speed minimum value and mean value are compared, significant for the readwrite performance of test solid state hard disc.
Wherein, when only having test result to meet the minimum value of I/O read-write frequency and minimum value that mean value is greater than or equal to respectively corresponding standard I/O read-write frequency and mean value under the minimum value of transfer rate and minimum value and mean value situation that mean value is also all greater than or equal to respectively corresponding standard transmission speed, the performance test results of current solid state hard disc is just qualified, otherwise the performance test results of judging current solid state hard disc is as defective.
