我们通常所说的光驱速度是指光驱的数据传输率,许多人在选购光驱的时候,往往只注意这一项指标,却没有认识到影响光驱速度的其它重要指标,因此形成了选购光驱的盲点。 1.数据传输率:数据传输率是光驱最基本的性能指标,它是指光驱在1秒的时间内所能读取的最大数据量。早期的光驱数据传输率只有每秒钟150K个字节,这也就是单速光驱。如今四十倍速光驱已成为主流产品。 2.平均访问时间:平均访问时间又称“平均寻道时间”,是指光驱的激光头从原来的位置移动到一个新的目标(光盘的数据扇区)位置并开始读取该扇区上
We usually say that the optical drive speed refers to the optical drive data transfer rate, many people in the purchase of optical drive, often only pay attention to this one indicator, but did not recognize the drive speed of the other important indicators, resulting in the formation of the optional optical drive The blind spot. 1. Data Transfer Rate: Data transfer rate is the most basic performance indicators of the optical drive, which refers to the maximum amount of data the optical drive can read in 1 second. Early optical drive data transfer rate of only 150K bytes per second, which is the single-speed optical drive. Now 40 speed optical drive has become the mainstream product. 2. The average access time: the average access time, also known as “average seek time,” refers to the optical drive’s laser head from the original location to a new target (the data sector of the disc) position and start reading the sector
