Considering the speed of CPU's and busses these days, software RAID can be a
lot faster than hardware RAID in many cases. I prefer hardware RAID myself
because of the simplicity (the OS doesn't need to know about the RAID
configuration), but I hear good results from people running on software
RAID.

Hope this helps you.
