Sequential Mixed Read / Write Workloads

In this series of tests, we measure mixed workload performance. We start with 100% read and then add data writes to the mix until we get to 100% writes, in 10% increments. We believe this will be the next major area SSD manufactures will address after performance consistency.

Sequential Mixed Workload Bandwidth

Until today, we've not tested a PCIe M.2 SSD that delivers good sequential mixed workload performance. A number of SATA 6Gbps drives have outperformed the XP941 and M6e products in this test. Samsung fixed the mixed workload issues with the SM951 and put the 80% read 20% write result outside of the reach of SATA products.

A document from Intel shows that 80/20 is a common mix for consumer workloads. We've adapted the mix to show heavy consumer mixed workloads for consumer products. The SM951 is, without question, the fastest consumer SSD I've ever tested.

Random Mixed Workload Response Time

The random mixed workload test also shows a significant improvement over existing PCIe M.2 products. It doesn't matter what angle we attack the SM951 from, it always comes out on top.
