用了多年的 PC,对速度的追求似乎永无止尽。当 CPU、内存、硬盘、显示卡等内部组件纷纷出新提速之后,我们面临的是外设如打印机、扫描仪工作的迟缓。其实这种迟缓也不全怪打印机、扫描仪本身,多数瓶颈实际在于计算机和外设之间的接口上。于是,高速的外设接口成了众望所归。 With years of PC, the pursuit of speed seems endless. When CPU, memory, hard drive, video card and other internal components have new speed, we are facing peripherals such as printers, scanners work slowly. In fact, this delay is not entirely strange printer, the scanner itself, most bottlenecks actually lies in the interface between the computer and peripherals. As a result, high-speed peripheral interface has become popular expectation.
