What can I use to benchmark the different raid set ups. I could do an all 
software raid trial and then an all hardware raid set up, (fresh install each 
time) and find out which is the best for my set up. Bear in mind I still

and the best way of learning is to roll up my sleeves and get my hands dirty.
