现在的硬盘转速越来越高,但硬盘工作时的噪音也越来越大。从技术层面上来看,硬盘的噪音主要来自主轴电机和寻道电机的运转。相比主轴电机而言,由于寻道电机的声音更像是一种“突发”性的声音来源,因此给人的感觉格外强烈。从1999年开始,硬盘厂商开始使用统一的AMM技术来降低硬 Now the speed of the hard disk is getting higher and higher, but the noise of the hard disk is also getting bigger and bigger. From a technical point of view, the hard disk noise comes mainly from the spindle motor and seek motor operation. Compared with the spindle motor, the sound of seeker motor is more like a “sudden” sound source, so the feeling is particularly strong. Since 1999, hard drive manufacturers have begun to use unified AMM technology to reduce hardware
