Crucial MX200 500GB & 1TB Solid State Drive Review

Testing – Anvil & PCMark Vantage
The next test is Anvil Storage Utilities, which is a really great piece of software. The SSD benchmark gives you scores for both read and write as well as a combined score.

We also use Anvil to test IOPS. The Threaded Read and Write tests are great for this. On each one we set the QD to 32.

We have now added PCMark 8 to our solid state drive benchmarks. We first run the typical Storage Benchmark.

From there we move on to the Storage Consistency test that can only be run from the command line. More or less this test degrades the drive down to a “dirty” state and then brings it back up to a clean state after given time to recover and running background operations like garbage collection and TRIM. All of our other benchmarks show performance of the drive in a “clean” state so it is an interesting view to see how to drive functions in a “dirty” state and how well it recovers.

This test takes almost a full 24 hours to run and includes workload traces from Adobe Photoshop, Adobe Illustrator, Adobe InDesign, Adobe After Effects, Microsoft Word, Microsoft Excel, Microsoft PowerPoint, World of Warcraft and Battlefield 3.

The different phases of the test are explained below:

Precondition phase
– Write the drive sequentially through up to the reported capacity with random data.
– Write it through a second time (to take care of over-provisioning).
Degradation phase
– Run writes of random size between 8*512 and 2048*512 bytes on random offsets for 10 minutes.
– Run performance test (one pass only). The result is stored in secondary results with name prefix degrade_result_X where X is a counter.
– Repeat 1 and 2 for 8 times and on each pass increase the duration of random writes by 5 minutes
Steady state phase
– Run writes of random size between 8*512 and 2048*512 bytes on random offsets for final duration achieved in degradation phase.
– Run performance test (one pass only). The result is stored in secondary results with name prefix steady_result_X where X is a counter.
– Repeat 1 and 2 for 5 times.
Recovery phase
– Idle for 5 minutes.
– Run performance test (one pass only). The result is stored in secondary result with name recovery_result_X where X is a counter.
– Repeat 1 and 2 for 5 times.
Clean up
– Write the drive sequentially through up to the reported capacity with zero data.

As you can see both the MX100 drives slowly come back up to a clean state, but not as fast as some of the other drives that we have tested.
