许多消费者在选购光驱的时候,往往只注意光驱的速度倍数这一项指标,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。实际上,人们通常所说的光驱速度是指光驱的数据传输率,单倍速光驱的传输速率为150kbps,4倍速光驱的传输速率为600kbps,12倍速光驱的传输速率为1800kbps。但决定光驱性能的主要指标除了数据传输速率外,还包括存取速率和数据缓冲区。所谓存取速率,是指计算机运行过程中阅读一位数据的
Many consumers in the purchase of optical drive, often only pay attention to the optical drive speed multiple of an indicator, but did not recognize the drive speed of the other important indicators, thus forming the optional optical drive blind spot. In fact, what people usually call the optical drive speed refers to the optical drive data transfer rate, single-speed optical drive transfer rate of 150kbps, 4x optical drive transfer rate of 600kbps, 12x optical drive transfer rate of 1800kbps. However, the main indicators determine the performance of optical drive in addition to data transfer rate, but also includes the access rate and data buffer. The so-called access rate, refers to the process of running a computer to read a data
