Description

A method for testing the impact of system-level vibration on hard disk performance

technical field

The invention discloses a method for testing the influence of system-level vibration on hard disk performance, belonging to the field of hard disk performance testing.

Background technique

A hard disk (English: Hard Disk Drive, HDD for short) is a non-volatile (non-volatile) storage device based on a hard rotating platter on a computer. It stores and retrieves digital data on a flat magnetic surface. Information is written to the disk by electromagnetic currents that change polarity through a write head that is very close to the magnetic surface. Because of its small size, large capacity, fast speed, and easy use, it has become the standard configuration of PCs.

The read/write speed of the hard disk is a key parameter to evaluate the performance of the hard disk. There are many factors that affect the read/write speed of the hard disk, including the design of the hard disk body, external channels, and system vibration. Among them, the impact of system shock on the hard disk lasts the longest. Especially when the computer is running, a sudden system vibration occurs, which is very unfavorable to the high-speed hard disk. Especially in today's practical applications, not only shaking or moving will produce system vibration, that is, when the servers are placed together, due to the operating principle of the mechanical rotation inside the server, it will itself produce a certain vibration. When the servers are placed together, the vibration generated by the rotation will produce a resonance effect, which will continuously superimpose and amplify the impact of the vibration, and finally cause the hard disk to fail to follow the perfect circle when writing or reading data. A circular path to read and write data will cause distortion or deviation from a perfect circular read and write path. Faced with this situation, it is necessary to adopt vibration protection technology and configure a vibration sensor. When the sensor senses an external vibration, it will transmit the message to the main control, and the main control will issue a fine-tuning signal at the same time, so that the operation of the hard disk can be completely in accordance with the The perfect circular path advances to ensure the correctness and efficiency of the user's data reading and writing. In order to improve the above method to protect the hard disk from the influence of system vibration, it is necessary to collect data on the impact of system vibration on the hard disk, so as to better implement the vibration protection technology and reduce the loss of the hard disk. The method is used to test the read and write capabilities of hard disks under different vibration levels, collect data on the impact of system-level vibrations on hard disk performance, and realize the evaluation of the impact of system vibration on hard disks. It has made preliminary preparations for improving vibration protection technology and reducing hard disk losses. very important.
