Fujitsu Quadro-M Series PCIe SSD Preview (Page 6)

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

Here you'll notice there are four drives on the chart, as we've added the OWC Mercury Accelsior to the mix. The Comay Bladedrive G24 and G.Skill Phoenix Blade both use a Comay PCIe to SAS RAID controller, and that controller has known issues with this specific test.

The Fujitsu Quadro-M 480GB is the first SSD we've ever had produce a reverse bathtub curve in this test. That means the drive is actually faster when reading and writing data at the same time than it is just reading or writing separately.

Sequential 80% Read / 20% Write Bandwidth

Papers published by storage companies show that an 80% read / 20% write mix should be used to measure consumer workload performance. Here we've isolated that mix and plotted the results. The Fujitsu Quadro-M performed very well here, outperforming both the ASUS RAIDR and OWC Accelsior.

Random Mixed Workload Response Time

The drive also performed reasonably well in our random mixed workload test. It's still no match for the enterprise controlled drives, but it fares well against the RAIDR.
