Analysis of SSD Acoustic Noise Generation Mechanism depending on NAND operation

Abstract

This paper investigates the acoustic noise generation mechanism of solid-state drives (SSD) by analyzing NAND operation and measures variation of voltage, vibration, and acoustic pressure depending on the NAND operation. NAND operation is measured with respect to number of overlapped banks during its operation. It is observed that frequency components of bank interleaving process during the NAND operation affect voltage, vibration, and acoustic pressure variation. It was shown that acoustic noise of SSDs greatly depends on NAND operation.
