I am not certain where you saw that, but it is incorrect, you can have however many 12gbps drives installed in a Virtual Disk and they will run at 12gbps. The only way that isn't the case is if a slower drive is used when configuring the Virtual Disk, which the controller would flag all the 12gbps drives as whatever the slowest drive speed is. ^CH
