A Study on the Disk Performance Comparison

Nowadays, Attention about how to effectively manage data according to vast amount of data is increasing. Also, concern about power consumption and CO2 generation with regard to green IT business is trends which growing up. In this paper, performance of HDD and DRAM-based SSD was analyzed when used as data storage. Performance comparativeanalyzed used Tool accordingly that make up a total of two kinds of environments and created three kinds of conditions, and comparative-analyzed power consumption amount and CO2 generated amount each of storage when experiment. Through this study result, when processing of low data I/O, use the product that using a HDD was judged beneficial. Used DRAM-SSD when stored and administered large amount data that is judged to be more effective which reduction in the time and power consumption reduction. Also, as a way which to handle of large amount data using a configured environment, SAN switch is considered more advantageous.
