Hi David, >> The choice of ZFS to use powers of 4 was likely not optimal, >> because to multiply by 4, it has to do two multiplications by 2. > I can agree with that. I didn't copy ZFS's choice here David, it was not my intention to suggest that you copied from ZFS. Sorry to have expressed myself badly. I just mentioned ZFS because it's an implementation that I know uses powers of 4 to generate triple parity, and I saw in the code that it's implemented with two multiplication by 2.
