It doesn't really matter that the hash collision is /less/ likely to ruin data than something in hardware as it adds an /extra/ layer of possible corruption, so you have a net gain in the possible corruption of your data. Now, if you could write it so that there was /no/ possibility of data corruption, than it would be much more acceptable as it wouldn't add any extra likeliness of corruption than already exists.
