8K Random Write/Read





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 5,000 seconds of preconditioning. The PM863 achieves a steady state at about 8,000 seconds of preconditioning.






8K random is a more demanding workload than 4K. As we typically see, performance is half that of 4K. 8K is a common transfer size in a server environment. The M510DC delivers good results, outperforming all but the SM863. Just a quick note on the 480GB M510DC. The 480GB capacity point of the M510DC is by far the best performing capacity point of the series, making it a better comparison than the 960GB M510DC. The PM863 again handily outperforms the 845DC EVO it is replacing.





The SM863 leads all the drives in our test pool up to QD8. The PM863 takes a slight lead at QD16-32. We again see a nice improvement when comparing the PM863 to the 845DC EVO. Micron's M510DC is outmatched by all three of the Samsung SSDs in our test pool. Samsung's SSDs are capable of delivering class leading read performance as these charts again illustrate.


Conclusion: Samsung's PM863 shows us why it is ideal for read-intensive workloads, managing to outperform the SM863 at QD16-32.
