Checked and you are perfectly right about the cluster size in windows depending, usually, by the size of the formatted device. The only limit seems to be 4K so the OP shouldn't be able to have a ntfs with cluster size of 6k and as you pointed out there would be waste of i/o of 25% for every operation.
Thank you for the clarification.
