Check this url:

it covers RAID in great detail. For you need, RAID 0 will give you  
the performance with no fault tolerance.
RAID 1 will give you the mirroring that you're looking for, with  
lower performance. RAID 7 seems to provide the best 'read/write'  
performance with fault tolerance but it's not an open standard, which  
means that you'd have to buy a proprietary controller.

Go down the list of RAID 'levels' and search for the one that gives  
you the best performance in sequential read/writes, since that's the  
operation you'll do the most in recording.
