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 PNY Prevail Elite didn't break into elite status, with 40MB/s single queue depth 4K read, but it was very close. The 4K reads scale well when the queue depths increase.
Here we get our first look at sequential write performance with incompressible data. The Prevail Elite gets close to 330MB/s, more than enough to move your Blu-ray movie at a brisk pace.
We want to point out the difference between the Vertex 3.20 and the Prevail Elite when working with 4K data. The Prevail Elite is just a little faster at QD 1, and we'll see how just a slight improvement in that space reflects on more sophisticated tests throughout this review.
