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.
As with the previous I/OPS test, the 4K read performance is nearly identical between the two Neutron drives.
The 4K write performance increase on the 256GB Neutron comes at higher queue depths. Sequential write performance on the other hand is much higher, a good reason to purchase the 256GB capacity model over the smaller 128GB size.
This test uses incompressible data. Just before the Neutron 256GB is the OCZ Vertex 3.20 240GB, a LSI SandForce based drive. You can see clearly see how the incompressible data gives the 3.20 240GB issues when trying to get going in the sequential test.
