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.
The 4K QD1 read performance is about half that of the Crucial M500 960GB. The BP4 scales well, achieving 50MB/s at QD4, but with the low starting point the scaling performance doesn't mean too much for enthusiasts.
The 4K write performance at QD1 is also around half of that produced by the M500. Here though, the BP4 doesn't scale as commands are stacked.
