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。
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.

一位来访者说:一些人说寻道者要体验仅对整体的冥想:如果一个人长期寻求灭掉思维,这将是悲惨的。
A visitor said: Some say that one should practice meditation on gross objects only: it may be disastrous if one constantly seeks to kill the mind.
所有版本均配备8MB的缓冲,他们正在与3.5毫秒,4.0毫秒的平均读取寻道时间额定平均写。

例如,一个15,000RPM驱动器的读操作需要大约3.5毫秒的平均寻道时间,写操作则需要大约4毫秒。
For example, a 15,000 RPM drive has an average seek time of approximately 3.5 milliseconds for reads and 4 milliseconds for writes.
如果有多个磁盘,那么把负载分配到不同的磁盘上是加快读写速度的有效方法,因为磁盘延迟的最大组成部分是寻道时间。
If you have several disks, splitting load onto separate spindles is an effective way of making reads and writes faster because the largest component of disk latency is the seek time.
当应用程序发出磁盘请求的速率快于磁盘返回数据的速率时,操作系统会让磁盘请求排队,还可能调整请求的次序以降低寻道时间。
The operating system queues disk requests when the applications issue them faster than the disks can return the data, optionally reordering them to minimize seeking.
由于它不是以高速旋转的磁盘作为存储介质,数据读写时不需要寻道时间,因此它有着传统硬盘不可比拟的顺序和随机存储速度。
Since it is not using high speed spinning disks as storage media like traditional hard disks, SSD obtains much higher sequential and random access speed than traditional hard disks.
WDS25硬盘与发烧级别的VelociRaptor产品有几分类似,不过前者的读写速度更快,其读取/写入寻道时间分别只有3.6ms和4.2ms。
Superficially, the WD S25 appears similarly to the VelociRaptor, but it has much faster read and write seek times at 3.6 ms and 4.2 ms respectively.
也许有一天,他再从海上蓬蓬地雨点中升起,飞向西来,再形成一道江流,再冲倒两旁的石壁,再来寻夹岸的桃花。
Perhaps, one day he would again rise from the sea in the form of fine vapors and travels westward, to form again a river that would dash by cliffs, and look for peach blossoms on the banks.
以利沙对他们说,这不是那道,也不是那城。你们跟我去,我必领你们到所寻梢的人那里。
And Elisha said unto them, this is not the way, neither is this the city: follow me, and I will bring you to the man whom ye seek.
