Last I checked some years ago, the RT-11 file system had the following
deficiencies:  (a) it was not hierarchical, i.e., no subdirectories;
(b) it forced files to be contiguous, so you easily ran out of space
for a file to grow even if there was plenty of free space on disk.

It's easy to design a file system with such defects and make it fast.
But that has nothing to do with UNIX or MS-DOS.
