Abstract
Solid State Drive (SSD) is based on Nand flash memory, so it has almost no factor for structure-borne noise as there is no mechanically moving parts. However, high-pitched noise from SSD has become a special issue raised from many users. Vibration tests were performed in this study to investigate the main cause of high-pitched noise from the SSD. Natural frequencies and its corresponding mode shapes were tested by modal testing. Also, sound pressure at certain points were measured when SSD is on reading and writing condition. The natural frequencies from both experiments were matched, which means the vibration of circuit board is main factor for high-pitched noise.
