The hard disk noise test method is applied to the hard disk noise test platform provided by any one of the embodiments, the hard disk fixing frame 1 is provided with a hard disk, and the hard disk noise test method specifically comprises the following steps:
step S1, in quiet environment, controlling the hard disk to perform sequential write operation, detecting and recording the IOPS value;
and step S2, controlling the hard disk to perform sequential writing operation, controlling the sound to start playing noise at a set frequency and an initial sound pressure level, gradually increasing the frequency and the sound pressure level until the IOPS value is reduced to a preset range, and recording the current sound pressure level as a critical sound pressure level and the current frequency as a sensitive frequency.
It should be noted that the quiet environment refers to a state where the audio 3 is not turned on, the controller detects and records an IOPS value (i.e., Input/Output Operations Per Second, representing the performance of the hard disk) in a state where the action of the audio 3 is excluded, the IOPS value represents the current state of the hard disk and can reflect a state of the read/write capability of the hard disk affected by noise, and the IOPS value recorded in the quiet state can be regarded as the basic performance of the hard disk and can be used for comparing with the IOPS value in the noise state to obtain the performance states of the hard disk 6 in different states.
In the operation process guided by the hard disk noise test method, the hard disk needs to be controlled to perform sequential writing operation or sequential reading operation, the IOPS value of the hard disk is tested in a noise-free state, the IOPS value of the hard disk is tested in a noise state generated by the sound 3, and when the value reaches a preset range, the numerical values of the frequency and the pressure level of the corresponding noise are obtained and are respectively used as the sensitive frequency and the critical pressure level, so that the sensitivity performance of the hard disk in the noise state is obtained.
Wherein, the Sound Pressure Level (SPL: Sound Pressure Level) is used for representing the size of the Sound Pressure; the above sequential writing refers to SW in fig. 7, i.e., Sequence Write.
In the present application, the sensitivity of hard disk noise refers to the degree of degradation of the hard disk data read-write performance under the influence of noises with different sound pressure levels and different frequencies.
The critical sound pressure level refers to that the performance of the hard disk generally decreases along with the increase of the excitation sound pressure level, and in the invention, the corresponding sound pressure level is the critical sound pressure level when the performance decreases to a certain threshold;
the sensitive frequency means that the noise sensitivity of the hard disk is different under the excitation of the noise with different frequencies, and in the frequency sweep test, when the performance of the hard disk is obviously reduced and reaches a certain threshold value, the corresponding frequency is the sensitive frequency.

if the IOPS value is not reduced to the preset range, judging whether the sound pressure level is the highest value;
if so, controlling to sweep frequency by one third octave of frequency, and recording the current frequency when the IOPS value is reduced to a preset range to obtain a set of sensitive frequencies;
if not, controlling the sound pressure level to increase according to the set increasing rate, and returning to the step of starting playing the noise.
Optionally, in the above process, after the current sound pressure level is the critical sound pressure level and the current frequency is recorded as the sensitive frequency, the method further includes the following steps:
judging whether the current frequency is the highest value; if not, controlling to sweep frequency by one third octave of frequency, and recording the current frequency when the IOPS value is reduced to a preset range to obtain a set of sensitive frequencies.
In the one-third octave frequency sweeping, the one-third octave means that the upper limit frequency of the frequency band is one time higher than the lower limit frequency of the frequency band and is an octave, and one octave is divided into 3 frequency ranges which are 1/3 octaves.
The frequency sweeping means that the frequency is sequentially output from small to large according to a specified frequency range.
In the above process, the method may further include adjusting an angle of the hard disk, or reinstalling the hard disk and performing the detection, so as to perform sequential operations on different hard disks.
In a specific embodiment, after the hard disk noise test platform is established, the hard disk 6 and the microphone are respectively fixed on the experiment table 5, the cable and the power supply are connected, the sensitivity measurement process aiming at a single hard disk comprises the steps that the computer controls the hard disk to start sequential writing operation, the IOPS value is recorded in real time, and the sound 3 starts to play noise according to the initially set lowest frequency and sound pressure level.
And in the playing process, increasing the sound pressure level according to the set step length until the IOPS value is reduced to be within the specified threshold range, recording the frequency and the sound pressure level of the noise at the moment, and taking the frequency and the sound pressure level as the sensitive frequency and the critical sound pressure level of the hard disk.
Then, the frequency sweep is started according to 1/3 octaves until all the sensitive frequencies in the set frequency interval are found, and the measurement of the sensitivity of the hard disk is finished.
The noise is pink noise, and each multiple wave path has equal intensity, i.e. has the same or similar energy in a certain range, so that the noise is stable noise and can be used for carrying out the test and ensuring the accuracy of the test.
During operation of the above method, the controller may be directly connected to the sound 3 to obtain the frequency at which the sound 3 emits sound.
The hard disk noise test platform and method established by the invention can measure the noise sensitivity of each hard disk 6, and are used for guiding the design of a server system, avoiding the sensitive frequency and the critical sound pressure level of the hard disk, reducing the problem of performance reduction of the hard disk, and improving the problem of hard disk damage caused by noise.
In addition, in the technical scheme of the invention, the relative positions of the hard disk 6, the microphone and the sound 3 can be adjusted, so that the relative positions can be adjusted and fixed to the optimal state, and the measurement accuracy is high; the hard disk fixing frame 1 and the microphone fixing frame 2 can be flexibly deployed to simulate the scenes in different case frameworks, the hard disk fixing frame 1 is compatible with 3.5 and 2.5 hard disks due to the 2.5-inch hard disk cushion block design, and the measurement applicability is wide; the microphone can be mounted in a clamping mode without tools or glue, so that the mounting time is saved, and the microphone is prevented from being damaged due to frequent dismounting.
