Abstract: “Compression-based schemes have been widely studied to improve the lifetime and performance of solid-state drives (SSDs). Recently, the most popular flash-friendly file system (F2FS) started supporting compression to maximize the lifetime of NAND flash-based storage. Also, compression-based computational SSDs (CSDs) are developed due to their high performance, transparency, and easy adoption. This paper will first study the compression of F2FS and CSD to understand their features. Then, cooperative compression (COCO) is proposed to optimize performance and power consumption based on the combination of F2FS and CSD. Experiments on real devices show that COCO has encouraged optimization.“
