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.




It would appear that USB 3.0 lacks support for queue depth changes found in NCQ. This is going to hamper the transfer of small files when you are pulling several from a drive using USB 3.0.




The Indilinx Barefoot lacks almost all support for NCQ while writing data, so the test shows the maximum speed across the chart for 4K queue depths. Here we can still see the wide difference in sequential and 512K speeds between the onboard USB 3.0 and the VIZO solution.
