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 Samsung PM853T averages 21,842 IOPS at 256 OIO; the 845DC EVO has a very consistent average of 19,678 IOPS at 256 OIO; the Micron M500DC tops the chart with an average of 21,133 IOPS, but experiences significant variability; and the Intel DC S3500 averages 19,400 IOPS at 256 OIO. The Samsung SSDs come in slightly lower than the M500DC, but with very consistent performance.
The PM853T leads the field in latency testing, pulling off the rare feat of delivering lower latency during lower IOPS performance.
The PM853T averages 3.85 watts; the 845DC EVO averages 3.55 watts; the M500DC averages 2.76 watts; and the DC S3500 averages 3.76 watts.
The PM853T averages 5,979 IOPS per watt; the 845DC EVO averages 5,465 IOPS per watt; the M500DC averages 7,676 IOPS per watt; and the DC S3500 averages 4,040 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 PM853T averages 28,207 IOPS, and the 845DC EVO averages a similar 28,054 IOPS at 256 OIO. The M500DC averages 18,650 IOPS, falling to the DC S3500 average of 23,664 IOPS.
The Samsung SSDs deliver great performance in this read-centric workload.
The PM853T averages 3.94 watts; the 845DC EVO averages 3.55 watts; the M500DC averages 3.21 watts; and the DC S3500 requires 3.8 watts during the fileserver workload.
The PM853T averages 1,082 IOPS per watt. The 845DC EVO scores M500DC scores 1,965 IOPS per watt, compared to 749 IOPS for the DC S3500.
