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 subject's 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 steady-state for the 2TB DC P4510 is achieved at 4,000 seconds of preconditioning. Average steady-state workload performance at QD256 is approximately 70.5K IOPS. We observe steady-state for the 8TB DC P4510 is achieved at 13,000 seconds of preconditioning. Average steady-state workload performance at QD256 is approximately 116.5K IOPS. The tight preconditioning patterns with few to no outlying IO's we see in the above charts is testament to the high QoS delivered by the DC P4510.
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 results of this test harken back to what we said earlier. Even though the 9100 MAX delivers far higher random write performance at queue depths of four and greater, performance at QD1-2 is much more important. This is why we see the DC P4510 delivering much better performance than the 9100 MAX within the typical operating region of QD1-9 even though this is a write-intensive mixed workload.
Conclusion (TL;DR): Performance where it matters. This is what Intel's DC P4510 is all about.
