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.
CDM uses incompressible data and gives us our first look at worst-case scenario performance. The 525 Series 30GB takes the biggest hit and doesn't scale nearly as high as the other 525 drives when the queue depths ramp up.
4K write performance with incompressible data really shows how the performance scales from the 30GB to the 240GB model rather well.
