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 SM843T averages 26,100 IOPS and features a nice, consistent performance profile. The P400M averages 21,075 IOPS, the Samsung SM843 has a very consistent average of 13,653 IOPS at 256 OIO, and the Intel DC S3700 averages 32,820 IOPS at 256 OIO.

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 SM843T averages 19,932 IOPS at 256 OIO. The SM843 averages 28,800 IOPS, and the P400M averages 21,196 IOPS, falling to the DC S3700 average of 24,551 IOPS.
