Understanding of Rewrite Penalty for Flash Memory SSD based High Performance Computing Real Time Systems

Sanam Shahla Rizvi and Tae-Sun Chung

Abstract—Flash memory is continuously been dominating on hard disk drives for high computing applications by last more than two decades. Currently the high capacity MLC flash SSDs are becoming center of attraction for modern real time systems to support their increasing storage and throughput demands. However, special hardware erase-before-write characteristics impose considerable performance penalty on flash storage systems. This paper evaluates the performance of modern MLC flash SSDs in their factory-fresh and used form from well known manufacturers and compares the response time and throughput results. Experimental results based on modern benchmark are provided and discussed to give the better idea to users for suitable storage devices for their real time systems.

Index Terms—Flash memory; high performance computing; MLC; real time systems; simulation; SSD.
