We precondition the drive for 16,000 seconds, or 4.44 hours, receiving performance data every second. We plot this data to observe the test subjects descent into steady state. We plot both IOPS and Latency. We plot IOPS (represented by blue scatter) in thousands and Latency (represented by orange scatter) in milliseconds. We observe the SM863 achieving a steady state at 4,500 seconds of preconditioning. The PM863 achieves a steady state at about 6,000 seconds of preconditioning. We observe extreme consistency with zero outstanding IO's from the SM863.
An Email Server workload is a demanding 8K test with a 50 percent R/W distribution. This application gives a good indication of how well a drive will perform in a write heavy workload environment.
The SM863 owns this test, delivering vastly superior performance in comparison to the rest of the drives in our test pool. The SM863 is serving up close to double the performance of Micron's M510DC at QD16-32. The PM863 shows once again that it is a worthy replacement for the 845DC EVO. Samsung's enterprise SSDs deliver remarkable mixed workload performance.
Conclusion: The SM863 cuts through this demanding workload with ease.
