Except that is not how NTFS operates. If the file contents are small
enough, and the blocksize large enough, the contents of the file will be
store in the MFT Directory Entry, not in a seperate file in the
filesystem. The size of the MFT block is based on the blocksize of the
underlying volume, so in cases of small files, it is actually _more_
efficient to have a larger blocksize:
