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.
4K reads nearly reach 30MB/s and the performance scales well from there.
4K writes are past 121MB/s, but we see the wall again as the queue depths increase. This test uses incompressible data which is worst case scenario for LSI SandForce based products. Looking at the ADATA SX900 on the chart, we see that the 120GB M500 is slower than SandForce SF-2281 controlled drives.
