Performance analysis of a hybrid system HDD-SSD

Abstract

The memory hierarchy in the latest computers is becoming subject of several significant changes. These changes try to improve significantly one of the most vulnerable points of computer systems inherited from one generation to another. The bottle neck ofcomputers is the communication between main memory RAM and HDD. This study willfocus on the benefit that provides the implementation of a hybrid system at the level of secondary memory. Through benchmarks which simulate applications that have significant dependence of the write and read processes will be analyzed through a machine where a hardware memory controller integrates SSD (Solid State Disk) and traditionaldisk HDD (Hard Disk Drive) together. Hybrid system performance will be compared with the standard system used to date.
