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 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.

 

OP and capacity have a lot to do with the results of this test. This is another test where the 240GB capacity of the BX300 we are testing is a disadvantage. However, the BX300 still delivers the goods very well. Only the Neutron XTi and the SX950 are able to deliver better performance.

 

 

 

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.

After testing the SX950, we were expecting the BX300 to deliver similar unimpressive sustained write performance, but to our surprise the BX300 handles it with ease. Very impressive sustained write performance to say the least.
