18TB "on paper" is usually 18 * 1000^4 bytes, so if you convert this
into "computer units" is ~16.37 * 1024^4 bytes.  If you then make an
ext4 filesystem on it with the customary 5% reserved for root, that gets
you down to 15.5TB, to which you also have to remove the space used by
inodes, so yes, probably about 15TB and of course, once you start
putting actual files ion the drive, additional space will be used by
directories and metadata.
