Using quota has more problems. Like exceeding quota make you unable to 
delete any file(like a deadlock).

Your use case, just showing how much space you used, may still hit some 
unusual problem like inaccurate number or even minus number, with 
performance drop.
But overall, it should be OK and meets your need.
