Question about 975X chipset RAID implementation

The following link suggests that the RAID implemented is software RAID in 975X chipset.

I would like to know if it is really software raid and would it not be slow?

And then exactly what is hardware raid?

  1. Yup, it's software RAID. Same as pretty much any other onboard RAID controller. Looks like hardware RAID at first glance, but don't let it fool you. A hardware RAID controller has its own built-in processor and memory. The hardware controlls all RAID functions, so it requires little resources from your system. Software RAID relies entirely on your system's CPU and RAM and runs within the OS. So the speed of the RAID depends on the speed of your system.

    The problem with software RAID is that since it runs within the OS, there's a chance the RAID could fail if your OS crashes. Hardware RAID doesn't have this problem.
  2. NVIDIA's nForce 430 chipset also offers RAID 0, RAID 1, and RAID 5. Even that is software RAID is it?

    Is the RAID logic implemented in the nForce430 drive which you install.

    Software RAID will be slower than hardware RAID?
