Moderate Workload Model

 

We categorize these tests as indicative of a moderate workload environment.

 

PCMark Vantage - Hard Disk Tests

 

Version and / or Patch Used: 1.2.0.0

 

The reason we like PCMark Vantage is because the recorded traces are played back without system stops. What we see is the raw performance of the drive. This allows us to see a marked difference between scoring that other trace-based benchmarks do not exhibit. An example of a marked difference in scoring on the same drive would be empty vs. filled vs. steady state.

 

We run Vantage three ways. The first run is with the OS drive 75% full to simulate a lightly used OS volume filled with data to an amount we feel is common for most users. The second run is with the OS volume written into a "Steady State" utilizing SNIA's guidelines. Steady state testing simulates a drives performance similar to that of a drive that been subjected to consumer workloads for extensive amounts of time. The third run is a Vantage HDD test with the test drive attached as an empty, lightly used secondary device.

 

OS Volume 75% Full - Lightly Used

OS Volume 75% Full - Steady State

Secondary Volume Empty - FOB

There's a big difference between an empty drive, one that's 75% full/used, and one that's in a steady state.

The important scores to pay attention to are "OS Volume Steady State" and "OS Volume 75% full." These two categories are most important because they are indicative of typical of consumer user states. When a drive is in a steady state, it means garbage collection is running at the same time it's reading/writing. This is exactly why we focus on steady state performance.

 

Better low queue random performance allows the SM951-NVMe to deliver the best performance in this test. The 400GB 750 has the best performance of the Intel drives in a lightly used state, but the 1.2TB 750 delivers more performance than the 400GB version in a steady state.

 

 

PCMark 7 - System Storage

 

Version and / or Patch Used: 1.4.0

 

We will look to Raw System Storage scoring for an evaluation because it's done without system stops and therefore allows us to see significant scoring differences between drives.

 

OS Volume 75% Full - Lightly Used

The 400GB 750 is basically delivering the same performance as the 1.2TB 750. The Samsung PCIe drives with their superior low QD random read performance easily outperform the Intel PCIe drives in this test.

 

 

PCMark 8 - Storage Bandwidth

 

Version and / or Patch Used: 2.4.304

 

We use PCMark 8 Storage benchmark to test the performance of SSDs, HDDs, and hybrid drives with traces recorded from Adobe Creative Suite, Microsoft Office, and a selection of popular games. You can test the system drive or any other recognized storage device, including local external drives. Unlike synthetic storage tests, the PCMark 8 Storage benchmark highlights real-world performance differences between storage devices.

 

OS Volume 75% Full - Lightly Used

PCMark 8 is the most intensive moderate workload simulation we run. The 400GB 750 is performing at the same level as the 1.2TB 750. What we can take away from our moderate workload testing is that in a typical enthusiast OS setting the 400GB 750 Series is every bit as fast as the 1.2TB, despite its lower sequential read/write speeds.
