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 see incompressible data used in scaling queue depths at 4KB. The SX900 blasts well past Vertex 3.20 and V300. At a single queue depth SX900 delivers over 35MB/s, but the other drives catch back up as the queue depth increases. Reading sequential data that's incompressible is another area where the SX900 trumps the other two new SandForce based drives.
Of the three new SandForce based drives, the SX900 has a higher incompressible data write ceiling or brick wall as I call it. In the 120/128GB capacity size, SandForce based drives have a performance wall, you can easily spot every SandForce/MLC based drive in this chart by the horizontal line of performance, where the drive just won't give anything more.
