In this paper, we research the method for HDD I/O Performance improvement by Filter Driver & NAND FLASH Memory. This paper was started from N
AND FLASH Memory, and then we research the method for HDD I/O Performance improvement by Filter Driver.

The paper is organized as follows. In Section 2, we introduce the HDD I/O Performance improvement by Filter Driver. In Section 3, we introduce the NAND FLASH Memory. In
