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 we are looking at 4K and NCQ performance. OCZ states in the Octane literature that the drive was optimized for 1-3 queue depth, but we only test with 1, 4 and 32 depths. When compared to the Vertex 3 120GB we see the Octane is a little slower at 4K, but ramps really well when the commands are stacked.
Like many of the smaller drives, the Octane hits a wall when writing data at depth. That wall seems to be right around 72MB/s which is around 100MB/s slower than the 120GB Team SandForce drives.
