The only practical use of which I'm aware is if you are doing I/O benchmarking and you want to test the actual speed of the I/O, as opposed to the efficacy of the pagecache. On a normal system, the pagecache dramatically increases performance by not having to go to disk for filesystem data or metadata, depending on what cache you're looking at.
