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 P420m averages a respectable 112,930 IOPS at QD256, relying upon its superb read performance to outweigh the slower write performance. In mixed read/write scenarios, the P420m can provide excellent performance due to the fast write speed. The P320h leverages it SLC-powered random write speed to provide an amazing average of 228,626 IOPS at QD256.
The P320h utilizes its ultra-low latency SLC to best the P420m easily in the latency test.
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 P420m shows it strengths in heavy read workloads, beating the P320h handily with an average of 166,847 IOPS at QD256.
The P420m squeaks ahead of the P320h at higher queue depths, while the P320h eeks out a win at the lower queue depths.
