What effect does the hard disk speed have on the hard disk performance index

and other negative effects. The speed of the notebook hard drive is lower than the desktop hard drive, which is partly affected by this factor. Notebook internal space is small, notebook hard disk size (2.5 inches) is also designed than desktop hard disk (3.5 inches) small, speed increase caused by the temperature rise, the notebook itself to the thermal performance of the

Higher requirements, noise, and must take the necessary noise reduction measures, these are the notebook hard disk manufacturing technology put forward more requirements. At the same time, the increase in speed, while the other maintain the same, it means that the power of the motor will be increased, unit time to consume more electricity, battery working time shortened, so that notebook portability is affected. Therefore, notebook hard drives generally use a relatively low speed 5400rpm hard drive.

Technology

The speed is changed with the improvement of the hard drive motor, now the liquid bearing motor (FLUID dynamic bearing motors) has completely replaced the traditional

Ball bearing motor. The liquid bearing motor is usually applied to the precision machinery industry, it uses the mucous membrane fluid oil bearing, replaces the ball with the oil film. This will avoid gold.

The direct friction of the genus surface minimizes the noise and temperature, while the oil film can absorb the vibration effectively and improve the anti-seismic ability, which can reduce the wear and prolong the life.
