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.
CDM is our last synthetic benchmark; we use it to observe 4K and native command queuing performance. The SF-2281 delivers around 10MB/s more than the SF-1200 controller, but 4 depth 4K is around 30MB/s lower. That changes when we get to a queue depth of 32. The 32 depth 4K read goes all the way up to around 215MB/s, an improvement of 60+ MB/s over last year's consumer SandForce drive.
The 4K writes on the OWC Mercury Extreme Pro 6G are faster than last year's consumer SandForce controller across the board. Here we see the Pro 6G outperforming the Crucial m4 and all other Marvell based SSDs on the chart.
