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.




Here we carry over the 4K scaled queue depth testing into CrystalDiskMark. Like the previous page, we see the 4K reads starting off low and then scaling at a slow pace.




Here we see our first real test with incompressible data being written to the drive. The sequential test shows the V3.20 at 132MB/s, but the V300 with Toshiba Toggle 19nm achieves 172MB/s. The V300 also has a higher 120GB 'brick wall'.
