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.
Here were looking at 4K and native command queuing performance. Across the board all of the leading drives are capable of between 32 - 39MB/s in 4K read performance. When you get to QD:4 the Biwin NuvoDrive NX takes a 30 to 40MB/s lead on the SandForce drives, but is around 20 - 30MB/s slower than the Marvell based drives from OCZ (Vertex 4) and Plextor (M3 Pro).
The 4K write speed recorded in our test with the early sample produced a 141MB/s score which is nearly identical to the Vertex 4 256GB drive. The QD:4 and QD:32 performance went up to 271MB/s. The original Barefoot drives didn't scale from QD:4 to QD:32 either.
A bit more interesting is the sequential performance in this test. The NuvoDrive NX dominates this test and the reason why because this test uses incompressible data.
