What I don't get is that RAID5 is a simple xor. It should be a trivial operation, that would be equally trivial to hardware accelerate.
What I am the most puzzled by is how parity (i.e. RAID5) is so bad in windows storage space. A modern CPU should be able to xor data at several gigabytes per second. And it seems that even by optimizing the block sizes, windows storage space parity caps at a couple hundred MB/s.
