128k Sequential Read/Write
128k sequential speed reflects the maximum sequential throughput.
The Intel DC P3700 delivers 2,392 MB/s at 256 OIO, the HGST FlashMAX II trails with an average of 2,664 MB/s at 256 OIO, and the P420m leads with 3,186 MB/s. The DC P3700 falls quite a bit in this workload, while the P420m flirts with maxing out the PCIe 3.0 bus.
Latency testing shows the P420m holding a substantial advantage with sequential read workloads.
The P420m provides excellent Latency v MB/s performance.
Sequential write performance is important for workloads such as OLTP logs, OLAP, batch processing, and transaction logging.
The DC P3700 stretches its legs and delivers 1,818 MB/s in the sequential write workload. The HGST FlashMAX II writes at 1,091 MB/s at 256 OIO and the P420m brings in the rear with 647 MB/s.
The DC P3700 enjoys a considerable lead in sequential latency.
The DC P3700 distances itself from the pack with all of its performance coming at very low latency.
The DC P3700 scores very well with a 100% write workload, but drops significantly at a 90% write workload. It also encounters some turbulence in the 60-70% range.
