ABSTRACT:
A computer memory system and method utilizes a disk drive as a caching device to overcome the size and cost limitations of conventional semiconductor cache memory. Despite providing somewhat slower access times than semiconductor cache memory, utilizing one or more disk drives as a caching device allows enhanced performance to be maintained for longer times under sustained loads by effectively decreasing the latency of the primary storage device, combining relatively small random requests into larger sequential requests, balancing the input/output ("I/O") load over several disk devices and/or canceling duplicate writes.
