A disk cache improves server perfonnance by using memory to temporarily store data that is moving between programs and the hard disk. There are two types disk caching: read caching and write caching, also known as lazy write.

With write caching, data destined for the hard disk is temporarily stored in the cache until the server can write other activities. Write caching can also save writes to the disk by updating data while it is still in the cache.
