4K 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 decent 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 steady state is achieved at 3,000 seconds of preconditioning.
There is no contest here, the M510DC delivers vastly superior 4K random write performance. At QD4, the M510DC's performance maxes out near 24K IOPS and holds steady through QD32. The 845DC EVO displays very little variability, holding steady at around 14.5K IOPS at QD1-QD32.
4K random read performance of the two drives is much closer to one another than 4K random write. The 845DC EVO displays better performance from QD1-QD8. At QD16, the M510DC takes a small lead over the 845DC EVO. At QD32, both drives are essentially delivering the same performance.
Conclusion: The M510DC will perform better than the 845DC EVO in a pure 4K random workload environment.
