8K random read and write speed is a metric that is not tested for consumer use, but for enterprise environments this is an important aspect of performance. With several different workloads relying heavily upon 8K performance, we include this as a standard with each evaluation. Many of our Server Emulations below will also test 8K performance with various mixed read/write workloads.

 

The average 8K random read speed of the P420m weighs in at 404,519 IOPS at QD256, besting the P320h with its average of 374,638 IOPS.

The 8k read latency results again reflect the same hiccup we noticed with QD8 for the P320h, but the remainder of the results are within expectations, with the P420m providing a better latency range under random read workloads.

The P320h averages 103,204 IOPS, with the P420m trailing behind at an average of 56,070 IOPS.
