Crucial MX200 500GB 2-Drive SSD RAID Report

By: Jon Coulter | RAID in Storage | Posted: Mar 16, 2015 2:10 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, 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 - 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 it's reading/writing. This is exactly why we focus on steady state performance.

 

This time our MX200 array takes a backseat to our MX100 array. Our Mx200 array puts up the second best empty performance we've seen to date, surpassing our MX100 array in this category. Steady state performance is a little lower than we expected to see, but still very robust. Our MX200 array is able to defeat our current RAID champion, Intel's 730, in the steady state category, but our 850 Pro array runs away with this test.

 

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

In this round of testing, our MX200 array finishes in the bottom half of the arrays on our chart. Again, our MX100 array is able to put up better numbers. Let's see if this trend continues or if the MX200 has enough improvements under the hood to make a comeback in testing that we place a higher importance on.

 

 

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. Our MX200 array comes back with a vengeance, decimating all but our Intel 730 array. The MX200 scales in an array slightly better than the MX100. The Toshiba flash-based arrays and our Samsung flash-based array aren't even close. This is what we love about IMFT NAND, it typically scales far better than competing flash.
