Intel DC P3700 800GB NVMe vs. Intel 730 Series SATA SSD RAID Report

By: Jon Coulter | RAID in Storage | Posted: Jul 17, 2014 2:00 pm

Light Usage Model

 

We are going to categorize these tests as indicative of a light workload. If you utilize your computer for light workloads like browsing the web, light gaming, and office related tasks, then this category of results is most relevant for your needs.

 

 

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/Array 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 (Rev 1.1). Steady state testing simulates a drive/array's performance similar to that of a drive/array that has been subjected to consumer workloads for extensive amounts of time. The third run is a Vantage HDD test with the test drive/array attached as an empty, lightly used secondary device.

 

OS Volume 75% Full - Lightly Used

OS Volume 75% Full - Steady State

Secondary Volume Empty - Lightly Used

As you can see, there's a big difference between an empty drive/array, 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/array is in a steady state, it means garbage collection is running at the same time that it's reading/writing. This is exactly why we focus on steady state performance. Here we can see that the DC P3700 is tuned for enterprise workloads.

 

 

PCMark 7 - System Storage

 

Version and / or Patch Used: 1.4.00

 

We will look to the Raw System Storage scoring for RAID 0 evaluations because it's done without system stops and therefore allows us to see significant scoring differences between drives/arrays.

 

OS Volume 75% Full - Lightly Used

More of what we saw with Vantage testing. The DC P3700 is tuned for enterprise workloads and because of that, it's easily bested a 2-drive array when subjected to the type of consumer workloads that comprise Vantage and PCMark 7.

 

This is a little deceptive because Intel's 730 is so much more powerful than any other drive we have tested to date when RAIDed. There are many other arrays that cannot exceed 11,000 points, even when we RAID six of them together.

 

 

PCMark 8 - Storage Bandwidth

 

Version and / or Patch Used: 1.2.157

 

We use the 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

Usually we do not see a contradiction in our light usage model-testing suite; however there it is. The DC P3700 smokes all of our arrays; delivering the best performance we have ever seen from this test. I am more inclined to toss out Vantage and PCMark 7 and take this result as a standalone indication that the DC P3700 can actually outperform any motherboard based array in a light usage scenario.
