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 are looking at 4K and native command queuing performance. This test uses incompressible data so the SandForce based drives don't have the opportunity to take advantage of their complex compression algorithms.The single command 4K read delivers impressive performance that is very close to the SandForce based drives. When things start to get stacked up the BP3 really takes off, delivering nearly 30MB/s more read performance at 4 requests. The SandForce drives retake the lead at 32 requests though by a small margin.




The Phison S8 controller does not take advantage of NCQ when writing data to the drive. Here we see 45MB/s 4K writes across the board regardless of queue depth.There is a glimmer of hope, though. Since this test uses incompressible data we can compare the sequential write speed of the Phison to the SandForce in this test. In the sequential test the Phison outperforms all of the SandForce and for that matter, every other mSATA SSD in our chart.I don't foresee Phison enabling NCQ writes with the new firmware, but we are hoping for the best. Phison controllers tend to lack this feature regardless of form factor.
