Datatransfer times are typically fractions of a millisecond, so rotational latency and seek time are the primary sources of disk latency on a physical HDD.
数据传输时间一般几毫秒,所以旋转延迟时间和寻道时间是一个物理hdd的主要磁盘延迟时间来源。

Latency: the time between initiating a request for data and the beginning of the actual data transfer.
