PC的整体性能高低是由CPU、主板、内存硬盘等多方面因素决定的。其中磁盘子系统也是重要的影响因素之一。目前随着计算机整体技术的提高,硬盘技术同样也有更进一步的发展,例如Ultra DMA66技术的应用等等,那么究竟什么是Ultra DMA66?它的性能如何?怎样应用Ultra DMA66,有哪些品牌的硬盘是支持Ultra DMA66的呢? 何谓Ultra DMA66 首先让我们来谈一下DMA(Direct Memory Access,即直接内存存取)。目前硬盘普遍采用IDE接口,使用美国国家标准协会(ATA)制定的标准,故亦被称为IED/ATA。随着技术的发展,后来又出现了ATA-2,FAST-ATA,FAST ATA-2,最高数据传输率达到了16.6 MB/s。
The overall performance of the PC by the CPU, motherboard, memory hard drive and many other factors. One disk subsystem is also one of the important factors. Currently with the improvement of the overall computer technology, hard disk technology also has further development, such as the application of Ultra DMA66 technology, etc., then what is the Ultra DMA66? What is its performance? How to use the Ultra DMA66, what brand of hard disk is Ultra DMA66 support Ultra? What is the first Ultra DMA66 Let us talk about DMA (Direct Memory Access, that is, direct memory access). Currently hard drive commonly used IDE interface, using the American National Standards Institute (ATA) to develop standards, it is also known as IED / ATA. With the development of technology, the ATA-2, FAST-ATA and FAST ATA-2 appeared later, and the maximum data transfer rate reached 16.6 MB / s.
