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.
In CDM we are looking at 4K and native command queuing performance. The Plextor M3 Pro reads single command 4K data at 35MB/s, on par with many other SSDs on the market today.
This test is more significant on the 128GB class of products than it is on the larger drives. The reason why is because for years the smaller 128GB SSDs hit a brick wall when the commands are stacked, shown here by the 120GB Vertex 3 and Crucial m4 128GB. The M3 Pro doesn't have the same limit; the drive just keeps pushing the limits as commands are stacked.
