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.
The driver battle shows no change, but here we see that the C300 is able to stretch its legs in sequential performance. Since the A-DATA S599 is targeted at a price point occupied by Indilinx Barefoot drives, this is a good time to start taking a look at how the two drives differ. Here we see that the SF-1200 has a huge lead in 4K performance. The Marvell SATA 6G C300 and the A-DATA SF-1200 controlled drives have nearly identical 4K and 4K QD32 performance. Once the queue depth is ramped up to 64 deep, the C300 is able to break away.
The same is true with the write performance at 4K. Also, once again we see that the Barefoot drives do not scale when the QD is raised. This shows that the Barefoot drives are not able to make effective use of NCQ like the next generation drives are able to.
