This test emulates Database and On-Line Transaction Processing (OLTP) workloads. OLTP is in essence the processing of transactions such as credit cards and high frequency trading in the financial sector. Enterprise SSDs are uniquely well suited for the financial sector with their low latency and high random workload performance. Databases are the bread and butter of many enterprise deployments. These are demanding 8K random workloads with a 66% read and 33% write distribution that can bring even the highest performing solutions down to earth.


The SM843 averages 13,481 IOPS at QD256, the P400m 20,413 IOPS, the DC S3700 33,546 IOPS, and the Optimus 36,837 IOPS.




The SM843 provides a tighter range of performance in this test, with 67% of I/O in the 10-20ms range and 32% in the 20-40ms range.




The SM843 averages 2.47 Watts, the P400m 2.75 Watts, the Intel 3.56 Watts and the Optimus 6.5 Watts.


This gives the SM843 5,448 write IOPS per Watt, the Micron P400m 7,422 IOPS per Watt, the Intel 9,418 IOPS per Watt, and the Optimus 5,659 IOPS per Watt.









The Webserver profile is a read-only test with a wide range of file sizes. Web servers are responsible for generating content for users to 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 that is hosting the websites, and thus the end user experience.


The SM843 averages 27,919 IOPS at QD256, the P400m 21,533 IOPS, the Intel 33,546 IOPS, and the Optimus 36,837 IOPS. All SSDs exhibit some variance, but taking into consideration the scale of the graph it is minimal.




The SM843 delivers 46% of I/O in the 8-10ms range, 27% in 10-20ms, and 24% in 6-8ms.




The SM843 averages 2.06 Watts, the Micron P400m 2.59 Watts, the Intel 2.24 Watts, and the Optimus 5.61 Watts.


This gives the SM843 13,542 IOPS per Watt, the P400m 8,304 IOPS, the Intel 10,600 IOPS, and the Optimus 5,071 IOPS.
