我能想到的理由是:即使SSD本身不产生大量的振动和辐射,但这并不代表其控制电路对振动和辐射不敏感,相反,可能是大量误码重复读取的jitter来源。
更何况,SSD的控制电路的(而不是flash颗粒本身)性能似乎并没有那么好,转一个说明固态硬盘的电磁辐射性能的网页
简单的概括,就是“Noise generated by the high-speed file transferring rate of an SSD device will interfere with WWAN and WLAN sensitivity. Moreover, noise generated by SSD controller also seriously interferes with 2G/3G, LTE, GPS, and Bluetooth. If the noise budget of SSD is not controlled at the R&D stage cautiously, the EMI issues will definitely arise and have a significant impact on computer systems and other interface.”
说白了,SSD可能比CD唱机的伺服电路产生的杂讯要更多得多,装个质量不好的SSD在机内,直接表现在听感上就是声音冷硬没生气了。Sotm Sata filter就是针对这个的产品。
