The rapid expansion of the Internet has led to an explosive growth in global data.New applications,such as the Internet of things and e-commerce,demand higher requirements for the latency and performance of data storage and processing.Thus,big data is not only more “big” but also more “fast”,and there is an urgent need to combine new storage media to build large-scale,high-performance storage systems.Two storage system design schemes were started,namely,flash storage and persistent memory storage.Their respective challenges were illustrated in detail,and the existing solutions were summarized.Finally,the future trends in the construction of data centers and storage systems were looked into.

Key words: storage system, flash memory, non-volatile memory
