If at one hand Convoy XL has as advantages requiring just one SATA cable to connect two drives to the PC and a SATA port on the motherboard that does not need to be RAID, the disadvantage is that the motherboard SATA port must be compatible with port multiplier technology, which allows multiple drives to be connected to the system through just one cable (click here to understand more about this technology).

All current Intel chipsets and AMD 790 chipset series are compatible with this technology and thus you won’t have any compatibility issues with motherboards based on Intel and AMD chipsets. NVIDIA chipsets, however, do not support this technology and thus are incompatible with Convoy XL (USB connection is still possible, but as you know this connection offers very low performance).

However it is not correct to say that all motherboards based on NVIDIA chipsets are incompatible with Convoy XL. Several high-end motherboards have a second RAID controller chip that controls additional SATA ports available on the motherboard, and usually this kind of chip is compatible with port multiplier. So if your NVIDIA-based motherboard has an extra RAID controller you can try installing Convoy XL on a SATA port that is controlled by it.
