I think he meant cluster size.

Look at number 64 and 32.
I know the documentation is for the previous version, but I believe the
principles still apply.
Note that since this sets the smallest allocatable size to a single
file, if your volume is meant for many small files you'll end up wasting
a lot of space. Perhaps the data in inode feature helps with that
though. I've used an increased cluster size on media volumes before
though and had no troubles.
