如何实现ATA133?
也就是Ultra DMA MODE 6我是KT333主板，支持ATA133
硬盘是三星的250G 8M IDE，也支持ATA133
可为什么还是显示Ultra DMA MODE 5呢？主板驱动都是最新的
硬盘接在主IDE的从盘上，主盘是希捷120G ATA100 Two devices on one cable - speed impact
There are many debates about how much a slow device can impact the performance of a faster device on the same cable. There is an effect, but the debate is confused by the blurring of two quite different causes, called here \"Slowest Speed\" and \"One Operation at a Time\".
\"Slowest speed\"
It is a common misconception that, if two devices of different speed capabilities are on the same cable, both devices\' data transfers will be constrained to the speed of the slower device.
For all modern ATA host adapters this is not true, as modern ATA host adapters support independent device timing. This allows each device on the cable to transfer data at its own best speed. Even with older adapters without independent timing, this effect only impacts the data transfer phase of a read or write operation. This is usually the shortest part of a complete read or write operation 单接133那个盘试试 没意义 你硬盘物理读写速率到不了133这么高 又不做raid0 ～ :awkward: 其实SATA接口那个速度基本都是浪费掉的 看了2F，我更是一头雾水了 大概就是用一条线接2个设备,传输速率是慢的那个设备的速率 可是2F的原文明说了这是一个误解啊...到底有没这回事啊 ATA133和100没什么区别。。。。。。。。。。。。:awkward:
