If it isn't running, and your machine works perfectly, you will only notice that RAM seems to disappear as more and more buffers are allocated and not freed. The dirty file buffers will get flushed to disk when the disks are dismounted during a normal shutdown. This presumes that everything works perfectly.
BUT.... If your maching ever crashes, depending upon how much file I/O you have done, you may be left with an unrepairable file-system because of data which was left in RAM during your last crash, that should have been written to disk.
