Crucial MX100 512GB 3-Drive SSD RAID Report

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, checking emails, 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 - 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 it's reading/writing. This is exactly why we focus on steady state performance. Our MX100 array defeats both our Extreme Pro and 730 arrays. At 75% full, only our 850 Pro array is delivering better performance.

 

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

Our MX100 array comes in fourth place. Toshiba's Q series Pro array dominates this particular test.

 

 

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

PCMark 8 is the most intensive light model workload simulation we run, and this time our MX100 comes in second to our 730 array. We love the MX100, and this is a perfect example of why we feel a MX100 array is one of the best bangs for the buck on the market. Think about it - for about $600 you get 1.5 terabytes of enthusiast grade OS performance that no consumer based PCIe drive can touch.
