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're looking at 4K reads and how the drive scales when commands are stacked up with Native Command Queuing. The 240GB Vertex 3 Max IOPS shows a massive improvement over the 120GB Vertex 3 when commands are stacked 32 deep. All three of the Vertex 3 drives perform within the margin of error in single depth 4K reads.

The 240GB Vertex 3 Max IOPS is able to scale much better when write commands are stacked compared to the 120GB Vertex 3.
