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% read and 33% write distribution that can bring even the highest performing solutions down to earth.
The Constellation ES.3 averages 201 IOPS at QD256, beating the other entries. The Seagate Enterprise Capacity exhibits tremendous speed in random workloads, easily winning the test.
The Constellation ES.3 offers up a wide range of access time, much like the other HDDs, but manages to have much of the I/O fall into the more desirable lower latency ranges.
The Constellation ES.3 averages 10.1 Watts during the test period.
The ES.3 averages 17.6 IOPS per Watt in our Database/OLTP testing.
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 Constellation ES.3 averages 187 IOPS at QD256, again leveraging the excellent read performance to win across the board at this test.
The Constellation ES.3 provides a lower latency threshold than the competing HDD's.
The ES.3 averages 10.9 Watts during the test.
The Constellation ES.3 averages 14.99 IOPS per Watt during the measurement window.
