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.


Crystal Disk Mark Tests




In a recent announcement the makers of CDM stated that they were making the 1000MB test the default benchmark so we have changed over from the 100MB test and started using the 1000MB test in our reviews.


USB does not take advantage of NCQ so queue depths do nothing for USB 2.0 or 3.0 performances. Here we do get a chance to observe the 4K numbers. Just like in the STR testing we see that the adapter allows our drive to keep a steady pace, but USB 3.0 is still not able to let the fastest SSD in the world run at native speeds.


Current NEC USB 3.0 controllers are not able to run at the full 5 Gbps speed that USB 3.0 is spec'ed at. We will need to wait for Intel to launch their USB 3.0 South Bridge for that to come about.
