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 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 is achieved at 4,000 seconds of preconditioning for a single drive; 5,000 seconds for a two-drive array. We do note a significant number of outlying IO's.
8K random is a more demanding workload than 4K. The XC100E5C outperforms Samsung's XS1715 from QD16 on up to QD256. Intel's DC P3700 delivers the second best performance of the drives in our test pool. The XC100E5C two-drive array is benefitting greatly from write caching in this test, delivering 2.4X the performance of a single XC100E5C. More importantly, the two-drive XC100E5C array is generating 78% more performance than Intel's DC P3608 at QD256.
As expected, the XC100E5C dominates Intel's DC P3700 from start to finish with the read portion of our 8K testing. At QD256, the XC100E5C outperforms the DC P3700 by 44%. The XC100E5C trails Samsung's XS1715 slightly up to QD128, at QD256 the XC100E5C surpasses the XS1715 by 8K IOPS. A single XC100E5C outperforms Intel's DC P3608 at queue depths of up to 32. The two-drive XC100E5C array again dominates the DC P3608 and the rest of the test pool, with the greatest performance disparity occurring at QD128.
Conclusion (TL;DR): The XC100E5C delivers far superior performance to that of the DC P3700 at all measured random read queue depths culminating in a 100K lead at QD256. The two-drive XC100E5C array again handily outperforms Intel's DC P3608 running in RAID 0 mode.
