Isn't XOR one of the most optimized routines in a CPU?  I recall reading 
a paper put out by Microsoft a few years ago where they benchmarked 
software RAID versus hardware RAID, and that software RAID wasn't as bad 
as everyone thought it should be precisely because a modern CPU can 
execute XOR so quickly.
