Quite clear - it's a case of arranging that OS chunks match stripes 
in the array so that when the OS write out a chunk, it will be a full 
stripe of the array and so just be a write to all drives without 
needing to read data first to calculate a new parity block.

Though the technicalities of working out the chunk size in the FS is 
beyond me at the moment !
