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 see 4K performance with incompressible data measured in MB/s. The Toshiba THNSNF delivers just under 22MB/s at QD1. The drive scales very well and nearly hits 84MB/s at QD4. Here we also see the sequential read speed at higher than QD1. The THNSNF does very well with more than 520MB/s.




The single queue depth 4K write performance is down quite a bit compared to most of the other drives on the chart. The sequential write performance though is very high, only second to OCZ's Vector.
