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.

Normally we just use CDM for the 4K and native command queuing performance, but since the test uses incompressible data, we can also use it to see how the Vertex 4 128GB compares to drives based on SandForce controllers. In the sequential test we see the V4 made it into the 500+ MB/s class with very few other drives.

 

The 4K QD1 performance is good, but we can see that other drives are a little faster. At a QD of 4 the Vertex 4 and Plextor M3 Pro take off and leave the SandForce drives behind. By the time we get to QD32 the V4 is in a class of its own delivering class leading 366MB/s performance.

For the last year and a half when looking at 120/128GB capacity drives we have to take into consideration the SandForce wall. This hard stopping point occurs only on the 60 and 120GB class drives. The Vertex 3 Max IOPS didn't have this same limitation, but most SF based drives did. This happens in CDM because this test uses incompressible data. The new Vertex 4 128GB does not have the limit as you can see in the chart. The drive is able to surpass every other 120/128GB class drive in 4K performance and takes a massive lead when the commands start stacking up.
