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.
On the previous page we saw the IOPS, now we can see how scaling queue depth scales in MB/s. Vertex 3.20 does well in 4K QD1, 35MB/s. Just as we saw on the previous page, the drive doesn't scale as well as the Vector or 840 Pro.
There is nothing to complain about when it comes to 4K writes, but this is also our first real look at the sequential incompressible data writes. Vertex 3.20 delivers around 333MB/s. The real comparison on this chart is to the Samsung 840, another mainstream drive and one that routinely sells out at my local Fry's. Vertex 3.20 rips the 840 non-Pro in incompressible data on this chart.
