Intel 750 NVMe 400GB U.2 SSD Bootable RAID 0 Report

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.

 

The 750 Series is more or less an enterprise SSD with consumer flash. This testing perfectly illustrates this fact. Enterprise class SSDs will always outperform consumer class SSD in this brutal test. Our 750 array easily leaves the competition in the dust.
