Nothing gets the heart racing like the thought of PCIe SSDs. Nothing gets the data flowing as fast either. But how does it affect your wallet?

CrystalDiskMark is a disk benchmark software.

 

Key Features:-

 

* Sequential reads/writes
* Random 4KB/512KB reads/writes
* Text copy
* Change dialog design
* internationalization (i18n)

 

Note: Crystal Disk Mark 3.0 is not available to the public yet, but the Technical Preview does allow us to test 4K performance at queue depths of 4 and 32 in addition to 1. The current release Crystal Disk Mark only shows us QD 1.

 


Read Tests

Normally we use CDM for looking at 4K performance, but this time the test will be used to point out some other details. Here we get a chance to look at the "tunable performance" from changing the chunk size on the Silicon Image RAID controller.

 

At the top of the chart is how our card was delivered and just under it was a configuration that I put in that changed the chunk size to 128 instead of 16. As you can see, we were able to raise the 4K read numbers by 60MB/s by modifying the configuration.

 


Write Tests

Our modified configuration also performed much better than the stock configuration in the write tests.

 

That concludes our synthetic benchmarks. Let's take a look at the real world tests and see if what we learned from the synthetics carries over to the real world.
