128K Sequential Write/Read
We pre-condition the drive for 6,500 seconds, or 1.8 hours, (12,600 seconds or 3.5 hours for the 8TB model) receiving performance data every second. A sequential steady-state is achievable in a much shorter span of time than a random steady-state. We plot both MB/s and Latency. We plot MB/s using blue scatter and Latency using orange scatter. We observe that steady-state is settles in at 1,000 seconds of preconditioning for the 2TB model and at 0 seconds for the 8TB model.
The 2TB DC P4510 is performing above its factory sequential steady-state write specification of 2,000 MB/s. Average steady-state write performance at QD256 is approximately 2,100 MB/s. The 8TB DC P4510 is also performing well above its factory sequential steady-state write specification of 3,000 MB/s. This is not surprising as Intel tends to be on the conservative side when dishing out factory performance specifications.
Comparing the above charts, we see the 8TB model delivering a much tighter, more consistent sequential write pattern than the 2TB model. You could say this is a visual representation of QoS.
As dominating as the DCP4510 was with our pure random workloads, it gets even better for the DC P4510 with pure sequential workloads. The 2TB model leads the field at QD1 and it, like the DC P3520 delivers full performance at QD1. Comparing the DC P4510's performance at the all-important QD1, we find that it is outperforming the non-Intel contenders by up to 3.5x. That is massive, and that is where it matters most.
The 8TB DC P4510 reaches its full performance at QD4, hitting a massive sequential write speed of 3,200 MB/s. 3,200 MB/s is by far the best sequential write performance we've ever seen from any SSD bar-none. And as we saw from our preconditioning chart, the 8TB DC P4510 is doing it with class-leading quality-of-service.
The DC P4510 dishes out more domination at QD1, where it is delivering at least 4x the performance of the non-Intel SSDs included in our test pool. Both the 2TB model and the 8TB model lead the field at all measured queue depths. Both models also exceed factory sequential read specs by a considerable amount, coming in at over 3,350 MB/s at QD32 and beyond.
Conclusion (TL;DR): The DC P4510 delivers the best sequential performance of any SSD that we've tested to date.
