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.
So far we've seen the Plextor M2 keep pace with other industry leaders, but now it's time to really start showing where the Plextor M2 differs from the pack. 4k performance has really become a hot topic with the introduction of the SSD. High IOPS and near instant data access has increased 4k performance in magnitudes. The M2 is able to read right around 16MB/s at 4k and this performance more than doubles when 4 commands are used. That number nearly doubles again at 32 commands.
This is a nice progression and one that we would look favorably upon if it wasn't for the introduction of the SandForce SF-2281 controller found in the OCZ Technology Vertex 3. For the most part, the Vertex 3 doubles the 4k performance of the Plextor M2.
Things get even worse for the Plextor M2 when it comes to 4k writes. Here we see the M2 delivering around 45MB/s at 4k which is very good, but there is no progression when commands are stacked at all. To add insult to injury, the Crucial m4, with another variant of the Marvell controller, does have working NCQ writes and just like the Vertex 3, blows the doors off the Plextor M2 in this area.
