70/30 Mixed Workload Test (Sledgehammer)

Version and / or Patch Used: Iometer 2014

Heavy Workload Model

This test hammers a drive so hard we've dubbed it "Sledgehammer". Our 70/30 Mixed Workload test is designed to simulate a heavy-duty enthusiast/workstation steady-state environment. We feel that a mix of 70% read/30% write, full random 4K transfers best represents this type of user environment. Our test allows us to see the drive descend into and reach a steady state as the test progresses.

Phase one of the test preconditions the drive for 1 hour with 128K sequential writes at QD32. Phase two of the test runs a 70% read/30% write at QD32, full random 4K transfer workload on the drive for 1 hour. We log and chart (phase two) IOPS data at 5-second intervals for 1 hour (720 data points). 60 data points = 5 minutes.

What we like about this test is that it reflects reality. Everything lines up, as it should. Consumer drives don't outperform Enterprise-Class SSDs that were designed for enterprise workloads. Consumer drives based on old technology are not outperforming modern Performance-Class SSDs, etc.

More than any other test we've run, this test best illustrates the advantage 3D XPoint memory has over NAND. Unlike NAND, 3D XPoint is unaffected by the state of the drive during a workload. Steady-state pounds the NAND-based contenders, but has no effect whatsoever on Optane.

Sustained Sequential Write

Version and / or Patch Used: Iometer 2014

Heavy Workload Model

We write to the drive for 1 hour with 128K sequential writes at QD32. We log and chart megabytes per second data at 5-second intervals for 1 hour (720 data points). 60 data points = 5 minutes.

The Optane SSD 800P is unaffected when the span of the drive is written over and over. It maintains steady consistent performance that is slightly better than factory specs for the entire 1-hour test run.
