Description
Technical field
The present invention discloses a kind of method tested system-level vibrations and influenced on hard disk performance, belongs to hard disk performance test neck
Domain.
Background technology
Hard disk（English：Hard Disk Drive, abbreviation HDD）It is using based on hard rotary disc on computer
It is non-volatile（non-volatile）Storage device.It is in smooth magnetic surface storage and retrieval numerical data.Information passes through
The writing head close from magnetic surface is write by electromagnetic current on disk by electromagnetic current to change polarity mode.Since it is small, holds
Amount is big, speed is fast, easy to use, it has also become the standard configuration of PC.
The read or write speed of hard disk be assess hard disk performance a key parameter, influence R/W speed of hard disc because being known as very
It is more, including hard disk body design, foreign channels, system vibrations etc..Wherein system vibrations influence duration longest to hard disk.Especially
It is computer at runtime, unexpected system vibrations occur, are very unfavorable to the hard disk to run at high speed.Particularly now in reality
The vibrations for just generation system are not only shaken or move to business with upper, exactly when server is placed in together, due to server
The operation logic of internal machinery rotation, itself will generate certain vibrations, when multiserver is placed in together in the presence of all, this
Because of vibrations caused by rotating operation, therefore can empathize kind effect, the influence of vibrations is constantly superimposed amplification, finally can
Cause hard disk that can not remove reading/writing document according to the path of circular when being written or reading data, and distortion or inclined can be caused
Read/write path from circular.In face of this situation, it is necessary to take vibrations protection technique, Shock inductor is configured, works as inductor
When perceiving external vibrations, message will be communicated to master control, the signal of fine tuning is assigned in master control simultaneously so that the operation of hard disk can
To advance fully according to the path of circular, the correctness and efficiency of the data reading-writing of user are ensured.To improve above method
Hard disk is protected not influenced by system vibrations, it is necessary to the data that collection system vibrations have an impact hard disk, preferably to fall
Real vibrations protection technique, reduction hard disk loss, the present invention provide a kind of method tested system-level vibrations and influenced on hard disk performance,
The literacy of hard disk under different shock levels is tested, the data of influence of the collection system grade vibrations for hard disk performance are realized
Evaluating system vibrations influence hard disk, to improve vibrations protection technique, reduce hard disk loss and have done early-stage preparations, have very
Important meaning.

R/W speed of hard disc evaluating system grade shakes the influence to hard disk performance in dynamic grade.
The step 1. middle setting vibrations equipment shock levels when, be at least divided into 5 grades, prior level is first-class after being
The series of the 1/20-1/5 of grade.
The step 2. middle testing hard disk read or write speed when, at least record 10 data in same shock levels.
The step 2. middle testing hard disk read or write speed when, when data are recorded between different shock levels, in rear vibrations etc.
The data bulk ratio of grade record is 5 at least more in preceding shock levels.
The step is 3. middle to be carried out spss and/or eviews softwares being used to carry out data analysis during data processing, is passed through
Compare influence of the R/W speed of hard disc evaluating system grade vibrations to hard disk performance in different shock levels.
Usefulness of the present invention is：The present invention implements vibrations protection technique to need to improve, and reduces hard disk loss, provides
It is a kind of to test the system-level method for shaking and being influenced on hard disk performance, the literacy of hard disk under different shock levels is tested, wherein
At least it is divided into 5 shock levels, and shock levels are gradually strengthened, more reasonably to the read-write of hard disk under different shock levels
Ability is tested, and the data of influence of the different system grade vibrations for hard disk performance is collected, using analysis software to its data
It is analyzed, not only realizes influence of the evaluating system vibrations to disk read-write ability, be also to improve vibrations protection technique, reduce
Early-stage preparations have been done in hard disk loss, are had a very important significance.
