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 5,000 seconds of preconditioning for a single drive; 4,000 seconds for a two-drive array. We do note a significant number of outlying IOs.

With our configuration, we exceeded Techman's 4K random write factory specification of 115,000 IOPS. The XC100E5C delivers 4k random write performance that exactly matches that of Samsung's XS1715. The two-drive XC100E5C array delivers well over double the performance of a single drive in this test as we previously explained would happen in certain test scenarios. Intel's DC P3700 outperforms the DC P3608 at queue depths of up to 64. Our two-drive XC100E5C array eviscerates the DC P3608 at QD256 by 127K IOPS.

The XC100E5C outperforms Intel's DC P3700 across the board. Samsung's XS1715 outperforms the XC100E5C across the board. Our two-drive XC100E5C array hits a wall at QD128-256. We aren't exactly sure why the array hits this barrier, but this is the only test where it happens. Intel's DC P3608 beats all the competitors by over 100K at QD256. The XC100E5C performs very well, and very similar to Samsung's XS1715. The XC100E5C array outperforms the DC P3608 up to QD64.

 

Conclusion (TL;DR): The XC100E5C handily outperforms Intel's DC P3700 with 4K random reads. The reverse is true for 4K random writes.
