Solid state hard disc (Solid State Drives), referred to as consolidate disk, solid state hard disc (Solid State Drive) is with admittedly
State electronic store chip array and manufactured hard disk, are made up of control unit and memory cell (FLASH chip, dram chip).
Solid state hard disc is using flash memory as storage medium, and reading speed relative mechanical hard disk is faster.Solid state hard disc does not have to magnetic head, during tracking
Between be almost 0.The speed persistently write is very surprising.The fast of solid state hard disc is never only embodied in lasting read-write, random write
Writing rate is also exceedingly fast.Solid state hard disc does not have a mechanical motor and fan, and level of noise is 0 decibel during work.Solid-state based on flash memory is hard
Energy consumption and caloric value are relatively low in the operating condition for disk.Any mechanical movable part is not present in inside, and mechanical breakdown will not occur,
It is not afraid of collision, shock and vibration.Low-power consumption, noiseless, anti-vibration, low in calories, small volume, operating temperature range are big.
For user to SSD various requirement more and more higher, this is mainly manifested in the performance requirement aspect to hard disk.Either
The test of selection test that SSD has just been introduced or scene to hard disk, the performance of hard disk be all user most pay close attention to a bit, performance ripple
The change of dynamic uniformity is an important ring for test because the fluctuation situation of hard disk performance can directly affect user data read,
Writing speed, performance shake too conference directly affect the actual use of user.Therefore SSD uniformity test is either introduced
It is all essential that test is tested before still dispatching from the factory.In addition, it can also be read and write when handling user performance problem by observing
The situation of change of speed and iops within the unit interval comes the place of decision problem appearance, timely fault location.Therefore test
SSD uniformity is all an essential ring in terms of selection test and issue handling.
But present case is, producer when releasing SSD, it is general can only test SSD in the performance of SATA interface and
Each blocksize testing time is more, generally ten minutes, is to take the average value of ten minutes to be referred to each, Yong Huwu
Method sees the performance change more than ten minutes or longer time.And user can constantly carry out IO in actual use and handle up,
If only providing the average in a short time period, performance change situation in the whole period or far from enough can not be seen
's.As it is possible that within some period, the performance of hard disk can be very low, but is from the average behavior of whole period
Also it is possible, can thus misses the very low point of this performance, if user is exactly to carry out vital document at this time point
IO handle up, writing speed is reduced suddenly, and user is caused to be likely to cause unpredictable loss.
A kind of in view of the above-mentioned problems, method of test SSD uniformity of the present application.This method can be entered to the testing time
Row setting, the test before being dispatched from the factory to selection test, compatibility test, producing line are covered all around, while processing is used
The problem of family occurs can also position in time, contribute to the processing of customer problem.This method is simple and easy, no matter easily uses
It is that tester or producing line producers can be accomplished more fully to test.
The content of the invention
A kind of method of test SSD uniformity of the present application, specific implementation are to use FIO instruments, first specific
Test and carry out pretreatment action before each module automatically, this time pretreatment is not to be pre-processed according to the time of setting but sharp
Pre-processed with LOOP to loop, this ensure that pretreatment action must allow SSD to run completely one time, because conventional setting
The method of testing of time is not exactly accurate, and some modules may be tested less than can not determine that SSD comes into stable state in SSD.
It can ensure that SSD necessarily enters a stable state running through after two circles by LOOP, ensure that order read-write, the essence of random test
True property.Meanwhile in the method for testing each module test and pretreatment be an independent part, be use
What ssdtestnew.sh was chained up, this ensure that each test block is all independent, arbitrary mould can be changed according to demand
The operation of the thread of block or queue depth without influenceing other modules, it can also accomplish that variable is unique when verifying uniformity,
Considerably increase the flexibility ratio of test.After end to be tested, the log data that test obtains are analyzed, by using excle
Table or other means, check the uniformity of hard disk performance, if it find that problem be present, can be with timely processing.
