This test emulates 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 Micron M500DC tops the chart with an average of 21,133 IOPS; the Intel DC S3500 averages 19,400 IOPS at 256 OIO, and the Samsung SM843 averages 13,653 IOPS. The M500DC experiences significant variability, but even the low range of performance is higher than the nearest competitor for five of the six loads. This high performance is a direct result of the enhanced random write performance.
The M500DC averages 2.76 watts; the DC S3500 averages 3.76 watts, and the SM843 requires 2.43 watts.
The M500DC averages 7,676 IOPS-per-Watt; the DC S3500 averages 4,040 IOPS-per-Watt, and the SM843 averages 5,969 IOPS-per-Watt.
The Web Server profile is a read-only test 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 M500DC doesn't fare nearly as well in this read-centric workload as the other two contenders. The M500DC averages 18,650 IOPS, falling to the DC S3500 average of 23,664 IOPS and the SM843 average of 28,800 at 256 OIO.
The M500DC averages 3.21 watts; the DC S3500 requires 3.8 watts during the fileserver workload, and the SM843 pulls 2.7 watts.
The M500DC scores 1,965 IOPS-per-Watt, compared to 749 IOPS-per-Watt for the DC S3500 and 1,094 for the SM843.
