Software RAID requires the CPU and Kernel to do all the RAID processing, and 
can only work within the limits of the standard hardware - four IDE drives on 
most systems.  A hardware IDE RAID card may allow more than four, and allows 
you to have your boot drive and peripherals like CD drives too.  The processors 
on the card handle the RAID overhead.
