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.

We use CDM to look at the 4K and 4K Queue Depth performance. Other than the QD:32 test the results are almost identical. Even the QD:32 stays within the benchmarks' margin of error.

The write speeds at 4K also fall within the margin of error. Now that we are finished with the synthetics we can focus on the real world tests and verify what the early benchmarks have told us.
