Random Workloads


Our 4K random read/write workload consists of 4K transfers sizes, and results are measured in IOPS (Input Output Operations per Second). We utilize the eSATA interface for all testing, unless otherwise noted.




Above, we have our results from RAID 0 random read. As you can see, the 431U maintains performance through the QD scale, peaking around 98.5 IOPS. Moving over to RAID 0 random write, we find the 431U peaks at 67.5 IOPS at QD1.




RAID 5 maintained similar performance to what we found with RAID 0, topping out at 98 IOPS read, and 28.9 IOPS write.




Switching the 431U over to RAID 10, we found a slight increase in performance. Here, we have read IOPS at 112 at QD32, with write IOPS coming in at 56 at QD32.
