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 get our first look at incompressible data performance. The Zalman F1 reads 4K data at an impressive 40MB/s and that number increases as the native command queuing increases.

Writing incompressible data is more difficult for LSI SandForce drives since data that is compressible writes faster to the drives. Still, we observed an incompressible sequential speed of 308MB/s.

 

The 4K write speed peaked at over 135MB/s for a single command and ramped up to 263MB/s at QD32.
