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 this test we read 4K block data at queue depths. The biggest surprise is the 32 command depth read test where the Performance Pro hits nearly 290MB/s. The 4K 4 depth test was nearly 109MB/s read, which is a significant improvement on the SandForce 120GB drives.

Most 120GB/128GB drives hit a brick wall that is much lower than the limits of their larger capacity size versions. You can see the effect on the Vertex 3 120GB drive, the wall is just under 170MB/s. The Corsair Performance Pro 128GB has no such limit and is able to rocket away with around 100MB/s more write speed at high queue depth.

The trouble is actually getting into situations where you can use such a high queue depth. The 4 command depth is also higher than the SF-2281 controlled drives, but the margin is much lower.
