A disk cache is a mechanism for improving the time it takes to read from or write to a hard disk. A disk cache can also be a specified portion of random access memory . It holds data that has recently been read and, in some cases, adjacent data areas that are likely to be accessed next. Write caching is also provided with some disk caches.
