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.
The 4TB EVO delivers the highest average UOPS, winning this test. Because of its massive capacity, we filled (preconditioned) the 4TB EVO for three hours instead of the usual one hour, and it still won albeit with a lot of variability. The Mercury Electra again wins the futility award.
