- In this paper, we proposed Hot/Cold File Management Algorithm to maximize performance to environment combining a low speed I/O property HDD with a high speed I/O SSD. As a result to test by applying that algorithm, we confirm that performance get better multiples of 11.36(in case of block size=4k), multiples of 12.79(in case of block size=8k) and that performance is unrelated to a type of second disk (HDD, Flash-SSD, DRAM-SSD). © 2011 Springer-Verlag.
