Defining NVMe - Hands-on testing with the 1.6TB Intel P3700 SSD

By: Paul Alcorn | PCIe SSDs in IT/Datacenter | Posted: Jun 24, 2014 3:54 pm

OLTP Tests




The Intel P3700 leads the OLTP workload with 132,238 IOPS at 256 OIO. The P420m averages 106,403 IOPS, and the FlashMAX II weighs in with 121,240 IOPS.




The P3700 delivers lower latency at lower OIO while the FlashMAX II takes the lead at 128 and 256 OIO.




Comparing IOPS to latency illustrates just how much the P3700 distances itself from the competition. The P3700 occupies the space lowest and to the right, delivering the most IOPS at the lowest latency. At 1ms it delivers an outstanding 120,000 IOPS, while the FlashMAX II delivers 90,000 and the P420m weighs in at roughly 28,000 IOPS at the same latency. The P420m skims slightly above 1ms until it reaches 65,000 IOPS, still far below the performance from the P3700.


The HGST SSD800MH is still impressive; numerous 12Gb/s SAS SSDs stacked in a RAID configuration would be very competitive.




With a mixed workload, the P420m pulls slightly ahead in efficiency, possibly a hallmark of Micron's NVMe experience. The FlashMAX II fares well and is more competitive with mixed workloads. The DC S3700 is also surprisingly efficient in this workload.




Once again, the simplified driver stack and command set of NVMe, along with command coalescence, distances the P3700 from the pack in interrupt testing.
