Abstract

Due to the special write mode and limited lifetime characteristics of NAND Flash, a variety of technologies for the solid state disk flash translation layer (FTL) have been spawned. The existing Flash channel management method does not completely release the bandwidth of the Flash channel. In response to this problem, combined with a Nand Flash channel organization form of a solid-state disk, a multi-level parallel management mode is designed and implemented inside the SSD, which greatly improves the solid state. At the same time, a write distribution mechanism implemented in the upper layer software is designed. This mechanism can cooperate with the internal firmware of the SSD to realize the controllable write allocation of the host, strengthen the management ability of the user to the SSD, and realize the transparency of the data block.
