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

When we tested the Vertex 2 E (extended capacity) drives we noticed that the firmware on the drives was different than that on our previous tested Vertex 2 100GB. Here we see that the firmware did affect performance at the highest queue depth tested (QD: 32). The newer firmware on the Agility 2 is able to take the QD:32 4K test all the way up to 190MB/s which is very impressive.

 

Write Tests

Between the Agility 2 and Vertex 2 the 4K write speeds look almost identical. The Crucial RealSSD C300 256GB drive is able to write 4K data faster at queue depths of 4 and 32 but is slower when no NCQ is active.

 

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.
