The "sync" and "async" options have an impact on disk caching, yet the manual pages avoid the term "cache" - I assume being careful to be general about capabilities of the underlying kernel.
This does make it difficult for people trying to find options relating to disk cache behaviour, could the "sync" and "async" options be changed to refer to disk caches explicitly. For example, sync currently reads. All I/O to the file system should be done synchronously. In case of media with limited number of write cycles (e.g. some flash drives) "sync" may cause life-cycle shortening. Something like this may be more meaningful to a lot of users, it may oversimplify things with the use of the term "cache", but in most cases its the reference users are looking (searching) for. "All I/O to the file system should be done synchronously. This effectively removes kernel disk caching for the device causing more writes to occur. Media with limited write cycles, flash for example, will age prematurely.
