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 in 10% increments until we get to 100% writes. We believe this will be the next major area SSD manufacturers will address, after performance consistency.
Sequential Mixed Workload Bandwidth
None of the drives on this chart are perform well at sequential mixed workloads with the drives in full-on sequential steady state. This is a problem that carries over to SATA based products as well. We think most of the controllers in the first generation M.2 PCIe class of products are based closely on SATA. Both use the AHCI command set, which is bidirectional, but SATA is not a bidirectional interface. That explains why the drop off when mixing read and write workloads together reduces performance to such a large degree.
Sequential 80% Read / 20% Write Bandwidth
An Intel document states that consumer workloads are closer to 80% read and 20% write than any other mix. We use the same 80/20 mix to produce the data above. The Plextor M6e Black Edition 128GB scores the lowest in this mix, and by a relatively large margin.
Random Mixed Workload Response Time
In this test, we measure random reads and writes paired together to create a random mixed workload. The Plextor drives do much better here with the drives in a normal consumer steady state.
