RAID 5 Database/OLTP
This test emulates 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. 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 HGST array tops out at 82,952 IOPS at QD64, while the Micron array tops out at 74,517 IOPS at QD128.
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 Micron array again excels at this heavy workload. The HGST array tops out at 212,709 IOPS at QD256, while the Micron array reaches 263,447 IOPS.
The File Server profile represents typical file server workloads. This profile tests a wide variety of different file sizes simultaneously to simulate multiple users with an 80% read and 20% write distribution.
The HGTS array averages 119,434 IOPS at QD128, while the Micron P400m's average 101,782 IOPS at QD256.
