Large-capacity hard drives can no longer meet the demand. Flash memory, as a new type of storage medium, has the advantages of high-speed read/write, low power consumption, and high reliability, and is becoming more and more popular. However, there are still some bottlenecks in the read/write performance of flash devices, such as multiple erasures can reduce lifespan, and frequent erasure and write operations can affect memory performance.To solve this problem, this paper proposes a design and implementation scheme of flash translation layer based on layered management. It divides flash translation layer into fast cache layer, mapping layer and storage layer from the logic, which can effectively improve the read/write speed and performance of flash devices and prolong the service life of 精品文档---下载后可任意编辑flash memory. In terms of implementation, the design idea of microkernel-based operating system is adopted, C language programming is used, and FAT32 file system is used for testing and verification.The main contribution of this paper is to propose a design scheme of flash translation layer based on layered management, which can effectively improve the read/write speed and performance of flash devices and prolong the service life of flash memory. It has certain guiding significance and reference value for practical big data storage applications.Keywords: Flash translation layer; Layered management; Microkernel operating system; FAT32 file system; Performance optimization.
