Much depends on the contents of the files. Fixed size binary blobs

Note that the default zfs block size is 128K and so that will therefore
be the default dedup block size.
Most files are less than 128K and occupy a short tail block so
concatenating them will not usually enjoy the benefits of deduplication.
Most ? I think that is a bit of a sweeping statement. In know of some
environments where "most" files are multiple gigabytes in size and
others where 1K is the upper bound of the file system.
So I don't think you can say at all that "Most" files are < 128K.
