N2 - Due to the benefits of Solid State Drive (SSD), it has been called a pivotal technology on data storage systems. But, current device level I/O schedulers are not optimized for SSD. In this paper, we suggest a new I/O scheduler, called STB, to exploit the performance potential of SSDs. Our STB scheduler categorizes I/O requests into two groups and sets timers on each request. We implement STB scheduler in Linux 2.6.30, and the set of benchmark programs shows that STB scheduler provides better bandwidth up to 30% with low response time of each request.
