Abstract :
SSDs support various type of parallel IO mechanism. Thus, simulating IO latency of SSDs is difficult. In this paper, we develop SSD IO latency model for multi-channel, multi-way SSD. With the IO latency model, An SSD simulator can generate IO latency with a single thread. The IO latency models has 4% error rate compared with a real SSD, Intel X25-M.
