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 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.

 

Intel's 750 Series SSDs dominate this brutal test. The XG3 outperforms both the SM951 and the 950 Pro. This is a very good indicator that the XG3 can deliver better heavy workload performance in certain scenarios than Samsung's M.2 NVMe SSDs.
