从PIO发展到DMA、从DMA33发展 到ATA100,IDE硬盘的传输协议经历着几乎2年一变换的发展速度。从本身的结构来看,IDE硬盘无法满足高负载数据传输以及网络状态中多用户访问等环境下的应用。但是随着磁头以及磁盘制造技术的发展,IDE硬盘在CPU占用率以及数据传输速度也在逐步改善。目前众多硬盘厂商推出的单碟40GB IDE规格硬盘,在传输速率上基本可以超过40MB/s。如果单单考虑速度,这些产品在这一点上已经超过
From PIO to DMA, from DMA33 to ATA100, the IDE hard disk transfer protocol has experienced almost 2 years of change. From its own structure point of view, IDE hard drive can not meet the high load data transmission and network status in multi-user access and other applications. However, with the development of magnetic heads and disk manufacturing technologies, the occupancy of the IDE hard disk and data transmission speed are also gradually improving. At present, many hard disk manufacturers introduced a single platter 40GB IDE hard drive specifications, the transfer rate can be more than 40MB / s. If you think about speed alone, these products have been exceeded at this point
