Are you running 24 drives for capacity reasons or speed? I can't think of many RAID controllers that could push that many SSD's at full speed, so it must be for capacity. Have you thought of using fewer, higher capacity drives instead?

I little of both depending on the end use. Most of the times we use 3 PCIe raid controllers. Some cases 1 24 port controller works great. Also, we keep at least 2 or 3 in the hot swap mode for reliability.
