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 HDDs 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 percent read and 33 percent write distribution that can bring even the highest performing solutions down to earth.

The WD Xe ekes out the win among the trio.
The Web Server 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.
The WD Xe leans on its great read performance to deliver 389 IOPS at QD256; the AL13SE takes the lead with 399 IOPS, while the AL13SE trails with 381 IOPS.
The WD Xe averages 7.02 watts.
The WD Xe delivers an average of 54 IOPS per Watt.
