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 CDM we are looking at the 4k performance, but since the HPT RocketRAID did manage to hit sequential numbers higher than 2500 MB/s, you may get a little distracted. In all 4k read tests we found the RocketRAID outperforming the other controllers, but with so many more drives we really expected to see an all-out obliteration, which just wasn't the case.

The 4k write tests allowed us to find an issue with the RocketRAID's RAID 5 NCQ performance. Here we found that the controller doesn't effectively handle NCQ and we found no scaling at all when commands are stacked up. This was also observed in the AS SSD 4K NCQ test, but I am confident HighPoint will be able to work on this issue when they learn about it. In RAID 0 we see very good scaling with the 2760.
