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.




CDM allows us to look at 4K and native command queuing performance. Mechanical drives don't offer the same rip roaring 4K performance as SSD's because their mechanical nature means IOPS performance is low. Reading and writing several small files back to back is the most difficult task you can ask of a spinner.


The Hitachi GST 5K4000 is a little faster than the WD Red 1TB in 4K and QD4 4K reads. It loses a little ground to the Red when the commands are stacked 32 high.




The 32MB of cache seems a little low by today's standards and aids in the 5K4000 delivering low 4K write performance.
