长久以来,人们一直以CPU整体性能的高低来衡量整个计算机系统性能的强弱,后来随着多媒体技术的产生和发展,大家就越来越关注图形图像系统的性能。直到近几年,当我们使用着高速的CPU和高档的3D图形加速卡组成的PC在工作、学习、玩游戏等时候,却发现我们大部份的等待时间都花在硬盘的不停读写上。人们开始注意到了硬盘。于是,硬盘的传输协议便从原有的 PIO MODE 4—DMA/33发展到了如今的Ultra DMA/66,确保了硬盘不会影响整机性能的发挥。 目前的 Ultra DMA/66的硬盘已经取代了原来的 UltraDMA/33的硬盘成为了市场上的主流产品。各大硬盘厂商也都推出了多款支持DMA/66规范的产品。我们都知道要真正实现对Ultra DMA/66硬盘的支持,必须有相应的主板芯片组
For a long time, people have been measuring the overall performance of the CPU performance level of the whole computer strength, and later with the emergence and development of multimedia technology, we are more and more concerned about the performance of graphics and graphics systems. Until recent years, when we used high-speed CPU and high-end 3D graphics accelerator PC PC, working, learning, playing games, etc., we found that most of our waiting time spent on hard disk non-stop read and write on. People began to notice the hard drive. As a result, the hard drive transfer protocol from the original PIO MODE 4-DMA / 33 developed to today’s Ultra DMA / 66, to ensure that the hard disk will not affect the performance of the machine. The current Ultra DMA / 66 hard drive has replaced the original UltraDMA / 33 hard drive as a mainstream product on the market. Major hard drive manufacturers have also introduced a variety of support DMA / 66 specifications of the product. We all know that to truly support Ultra DMA / 66 hard drives, there must be a corresponding motherboard chipset
