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 an enterprise-class test designed to simulate a heavy-duty 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 enter 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. Phase two of the test runs a 70% read/30% write, 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.
Our dual 512GB 950 Pro array takes the win in this round of our testing. Intel's 750 finishes a close second, followed by the dual 256GB 950 Pro array. Adding a second drive into the mix doubles the performance with this demanding workload. Steady-state for both arrays is achieved at about 1,100 seconds into the 3,600 second run. With more time, the 750 may have caught our dual 512GB 950 Pro array, but it severely lagged behind for most of the test.
