Note: Crystal Disk Mark 3.0 is not available to the public yet, but the Technical Preview does allow us to test 4K performance at queue depths of 4 and 32 in addition to 1. The current release Crystal Disk Mark only shows us QD 1.
In the 4K read catagories we see that the Corsair F120 is able to outperform the Intel drive at QD4 but the two run very close at QD 32. Comparing the Force to the Indilinx controlled Nova we see that the Nova doesn't scale past a QD of 4 so a lot of performance is left off the table when compared to the SandForce drives that have all but replaced the Indilinx drives in performance and price point.
4K Write speeds are always quite an interesting topic. For a short while we were comparing the SandForce drives to the Crucial C300 256GB but when the 128GB C300 came our way we learned that there was quite a bit of a difference with the 128GB C300's write speed. Now we see that the Corsair Force 120GB is much closer to the 128GB C300 than we thought.
That concludes our synthetic benchmarks, let's take a look at the real world tests and see if what we learned from the synthetics carries over to the real world.
