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 WD Se averages 169 IOPS at QD256, matched closely by the Toshiba MG03SCA300.




The WD Se offers up a much wider range of latency recordings than the Toshiba HDD with this mixed workload.




The WD Se averages 9.25 Watts.




The WD Se averages 17.7 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 website, and thus the end-user experience.


The WD Se averages 154 MB/s at QD256.




The WD Se provides a wide range of latency variability, from 6ms all the way up to our maximum of 1000ms.




The WD Se averages 9.4 Watts.




The WD Se averages 16 IOPS per Watt.
