Cache on disk drives is a bug, not a feature. Performance-wise, it’s fast 
RAM hobbled by being located on the wrong side of a connection to the CPU 
that isn’t designed to transfer data at RAM speeds. And of course 
correctness-wise, it’s another complication in implementing the semantics of 
OS operations that are supposed to guarantee that data has been saved to 
persistent storage.
