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.
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 shows a massive improvement over the 120GB model when commands are stacked 32 high. Both Vertex 3 drives perform about the same with a single 4K write and when you look deeper into the chart you can see that the Vertex 3 is faster at this task than any other SATA 6G drive on the market.
The 240GB Vertex 3 is able to scale much better when write commands are stacked. Here we see that with 32 commands the larger drive is able to write at nearly 100MB/s faster. At first we didn't believe what we saw and went back to retest the 120GB Vertex 3, but the results were the same. The 240GB drive is quite a bit faster at this task.
