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.
OCZ's Vector 512GB delivers 35MB/s of 4K single queue depth performance and that increases to nearly 100MB/s at QD4. From there Vector just takes off and shows why it's the current king of SSDs, over 400MB/s at QD32 when reading data.
Vertex 4 started us down a path of blistering 4K write performance, but Vector improves upon the previous Indilinx Infused drive by more than 12MB/s at 4K QD1. Vector 512GB scales nicely all the way to QD32, Vertex 4 dropped off between 4 and 32 depth.
This test also uses incompressible data, the same data that bring Vertex 3 down quite a bit. Here we can see why OCZ started down its own path and acquired Indilinx and a chunk of PLX. Larger drives are the future and LSI SandForce's current offering doesn't perform well when working with high capacity sizes.
