Abstract: This paper presents a novel disk storage architecture called PRCD (prefetching RAM caching disk). It is used to collect small write requests and convert them into one large write request increase the writing of system function, and adopts the technique of data block prefetching to consumedly increases the reading of system the function.And then ,the paper introduces the method of PRCD's realization on the Windows NT platform.
