The average rotational latency is one-half of a revolution of the disk platter.

平均旋转等待时间指的是磁盘旋转一半的时间。

Data transfer 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。
