This test consists of Database and On-Line Transaction Processing (OLTP) workloads. OLTP is the processing of transactions such as credit cards and high frequency trading in the financial sector. Databases are the bread and butter of many enterprise deployments. These demanding 8k random workloads with a 66 percent read and 33 percent write distribution bring even the best solutions down to earth.
The HG6 trails the other SSDs, but offers a very consistent 13,787 IOPS at 256 OIO. The HK3R averages 20,332 IOPS, but suffers extensive variability. The Samsung 845DC EVO has a very consistent average of 19,678 IOPS at 256 OIO.
The HG6 offers steady latency performance, and improves at 256 OIO.
The HG6 averages 3.13 watts, the HK3R averages 3.52 watts, and the 845DC EVO averages 3.55 watts.
The HG6 averages 3,068 IOPS per watt, the HK3R averages 6,065 IOPS per watt, and the 845DC EVO averages 5,465 IOPS per watt.
The Web Server workload is read-only with a wide range of file sizes. Web servers are responsible for generating content users view over the Internet, much like the very page you are reading. The speed of the underlying storage system has a massive impact on the speed and responsiveness of the server hosting the website.
The HG6 offers impressive performance of 26,003 IOPS at 256 OIO, the HK3R averages 28,114 IOPS, and the 845DC EVO averages 28,054 IOPS.
The 845DC EVO and HK3R run neck and neck in latency vs. IOPS testing.
The HG6 averages 3.02 watts, the HK3R averages 3.88 watts, and the 845DC EVO averages 3.55 watts.
The HG6 averages 573 IOPS per watt, the HK3R averages 1,125 IOPS per watt, and the 845DC EVO scores 914 IOPS per watt.
