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 CDM we're looking at 4K and native command queuing performance. The SanDisk Extreme SSD 480GB delivers 36MB/s when reading 4K data. That jumps up to 72MB/s with QD4 and to 226MB/s at QD32.

The 4K writes suffer from the increased capacity size with the SandForce controller. Here we see just 20MB/s at 4K and that scales to just 38MB/s at QD4. It appears the SF-2281 has lost some steam when scaled to 512GB.

 

Newer controllers like the new LAMD and Marvell scale really well in products like the Corsair Neutron and OCZ Vertex 4.
