1987年，Jim Gray和Gianfranco Putzolu提出了五分钟交易内存的规则，以减少基于磁盘的I/O，当时DRAM和HDD的性价比特征。自从五分钟规则作为数据工程中的一个重要经验法则被引入以来，它已经得到了广泛的认可，并且已经被重新审视了两次，一次是在1997年，以解释HDD和DRAM的技术和经济比率的变化，另一次是在2007年，以调查基于NAND闪存的SSD对双层DRAM磁盘存储层次结构的影响。在本文中，我们回顾了五分钟规则自推出以来的三十年。首先，我们介绍了过去十年中主导存储硬件领域的变化，并重新计算了当今多层存储层次结构的盈亏平衡间隔。然后，我们提出了预测未来十年新兴硬件属性的最新趋势，并使用五分钟规则及其方法来预测这些趋势对数据管理系统设计的影响。
In 1987, Jim Gray and Gianfranco Putzolu put forth the five-minute rule for trading memory to reduce disk-based I/O on the then-current price–performance characteristics of DRAM and HDD. The five-minute rule has gained wide-spread acceptance since its introduction as an important rule-of-thumb in data engineering and has been revisited twice, once in 1997 to account for changes in technology and economic ratio of HDDs and DRAM, and again in 2007 to investigate the impact of NAND flash-based SSDs on the two-tier, DRAM–disk storage hierarchy. In this paper, we revisit the five-minute rule three decades since its introduction. First, we present changes that have dominated the storage hardware landscape in the last decade and recompute the break-even intervals for today’s multi-tiered storage hierarchy. Then, we present recent trends to predict properties of emerging hardware for the next decade, and use the five-minute rule and its methods to predict the implications of these trends on the design of data management systems.
