Modern computer systems use significant amounts of memory to improve performance. This feature has a significant impact on the disk cache. The experimental results in this paper indicate that the I/O streams at block-level demonstrate very strong spatial locality and negligible temporal locality. Therefore, prefetch in the disk cache can boost the performance. However, read/write cache can only achieve marginal benefits.
