CrystalDiskMark is a disk benchmark software that allows us to benchmark 4K and 4K queue depths with accuracy.
* 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.
The Corsair Force GS manages to score nearly 41MB/s in our CDM 4K QD1 test. As you can see that is the highest on the chart and even without this chart, it's pretty darn fast. Scaling to QD4 was just average, even for a SandForce controller and the QD32 result was average as well. For most consumers the higher queue depths are rarely ever achieved unless you're doing some serious multitasking.
The QD1 4K write speed result was 129.4MB/s, but SandForce has lost their massive 4K advantage to many of the newer Marvell based drives.
