RAID 0 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 bring even the fastest storage solutions down to earth.
The HGST RAID 0 array tops out at 424,551 IOPS, and the Micron P400m's reaches speeds of 253,274 IOPS.
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 Microns take the lead in this test. The HGST array averages 219,229 IOPS, while the Micron array tops out at 256,184 IOPS at QD256.
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 HGST array averages 241,072 IOPS, while the Microns' average 202,202 IOPS at QD256.
