CrystalDiskMark is a disk benchmark software that allows us to benchmark 4K and 4K queue depths with accuracy.

 

Key Features:-

 

* Sequential reads/writes

* Random 4KB/512KB reads/writes

* Text copy

* Change dialog design

* internationalization (i18n)

 

Note: Crystal Disk Mark 3.0 Technical Preview was used for these tests since it offers the ability to measure native command queuing at 4 and 32.

In CDM we're looking at 4k and NCQ performance. The Patriot Wildfire arrays scale when adding drives to the array as shown in the chart.

Wildfire also scales well when writing data on the Intel PCH.

 

This will be a good time to talk about stripe sizes on enterprise controllers. When we built our RAID 5 array we chose a stripe size of 64K, the default for the LSI 9265-8i. You can tune the controller for better random write speeds by using smaller stripe sizes. For better sequential reads and writes you can use a larger stripe size. 64 is right in the middle so our setup isn't turned for one over the other. Because of that we achieved poor 4K and NCQ results in this test.
