90年代后期,计算机外设的发展越来越快,令人目不暇接,在硬盘接口上也是如此。与传输速率令人不寒而栗的IEEE1394和达到80Mbps的SCSI技术相比,传统的EIDE接口已经不敷所需,Ultra DMA/33协议于是应运而生。理论上,它可以倍增EIDE的传输速率,让用户在几乎不增加成本的情况下提高整机性能。因此,这个协议去年一经推出就获得硬盘生产厂家的广泛支持。 《个人电脑》实验室这次测试了由WD(Western Digital)公司生产支持 The late 90s, the development of computer peripherals faster and faster, dizzying, in the hard disk interface is also true. Compared with the shuffling IEEE1394 and SCSI technologies that reach 80Mbps, the traditional EIDE interface is not enough, and the Ultra DMA / 33 protocol has come into being. In theory, it can double the transmission rate of EIDE, allowing users to improve overall performance with little or no additional cost. As a result, this agreement received widespread support from hard drive manufacturers as soon as it was introduced last year.
