We would like to thank the following companies for supplying and supporting us with our test system hardware and equipment: AVADirect, GIGABYTE, Cooler Master, LSI and Noctua.

We ran across two issues prior to testing. The first was one we thought about prior to the controller arriving and the second we didn't consider until after everything arrived.
The first and more complicated issue had to do with choosing a motherboard that had a nice data path for the PCIe 2.0 16 lane. Many of our high end motherboards on the Intel side of things use the NVIDIA NF200 bridge chip. We tested the controller with our X58A-UD7 and the results were not all that impressive due to the additional bridge chip. Then we tried the GIGABYTE 890FXa-UD7, a high end AMD based motherboard that features several PCIe 2.0 16x lanes, but it didn't deliver the performance we were looking for either.
We finally went back to basics and chose the Intel X58DSO, one of the first X58 chipset motherboards to hit the market. The X58DSO doesn't have all of the bells and whistles as the newer boards, but that played into our favour since many of those add-on goodies take bandwidth away from where we needed it.
The second issue we ran into had to do with power. Where do you get 24 SATA power connections that feed 5 volts? Standard 4-pin Molex to SATA adapters do not transfer the 5 volt power to the pins used on notebook drives, so 4-pin to SATA power adapters will not do you any good. Luckily, we have a few PSUs in the house and ended up using four of them to power the 25 SSDs used in the test (plus one more for the OS).
ATTO Baseline Performance
Version and / or Patch Used: 2.34
ATTO is used by many disk manufacturers to determine the read and write speeds that will be presented to customers.
With a single Crucial RealSSD C300 we see the HighPoint RocketRAID 2760 is capable of delivering higher performance than we see with our X58A-UD7 motherboard. Our baseline single drive performance with the 2760 is right around 370 MB/s read and 230 MB/s write.
