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 finally get to see the sequential read and write performance without the QD1 limit. The Vertex 460 delivers 514 MB/s in the sequential read test and Vector 150 delivers 539 MB/s.
The performance difference isn't much, but it is there. The same can be said about the 4K read performance. There is a small difference but not much.
We see the same thing in the write tests, Vector 150 is only slightly faster than Vertex 460. The Vertex 460 is just as much of a competitor to the Samsung 840 Pro as Vector 150.
