Database processing performance and energy efficiency evaluation of DDR-SSD and HDD storage system based on the TPC-C

This paper is to analyze and evaluate the data processing performance and energy efficiency of DDR-SSD and HDD storage system based on the TPC-C. Our experiments show that DDR-SSD storage is 22 times better than HDD storage in performance and 138% energy reduction effect in case of tpmC only. Furthermore, DDR-SSD storage is almost 300 times better than HDD storage in performance in case of simultaneous TPC and file processing test. This implies that SSD storage system demonstrate the desired target performance even in the multiple different tasks, while HDD storage system shows the performance advantage only on the same task.
