Figure 2 illustrates the actual storage position on the physical disk platter.
图2描述了物理磁盘盘片上的实际存储位置。
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。
All the sectors on a disk platter that can be read without moving the head constitute a track.
磁盘盘片在无需移动磁头的前提下即可读取的所有扇区组成一个磁道。
This is due to how WebSphere MQ accesses the disk: essentially, MQ can only respond to the commit when the relevant part of the disk platter has spun past the drive head.
这归因于WebSphereMQ访问磁盘的方式：实质上，MQ只能在磁盘的相关部分转过磁盘头时才响应commit 。
Now, the most commonly used enterprise hard disk drives (HDDs) are limited by the rate of head movement, the speed of the spinning platter, and seek latency.
现在，大多数常用的企业硬盘驱动器(HDD)都受到磁头移动速度、盘片旋转速度和查找延时的限制。
Regarding buffering of metadata, VxFS allows the user to specify that the metadata, which is usually written to the log on the platter, would not be synchronously written to disk.
对于元数据的缓冲，VxFS允许用户指定元数据(通常写回到磁盘上的日志中)不会被同步写回到磁盘。
The output device might be a hard disk, for instance, and writing to the hard disk involved moving the write head around and waiting for the platter to spin to the right place.
输出设备可能是硬盘，例如，和写作涉及的硬盘将写头，等待盘片旋转到正确的地方。
The output device might be a hard disk, for instance, and writing to the hard disk involved moving the write head around and waiting for the platter to spin to the right place.
让我们考虑硬盘作为输出设备。写入硬盘内存相比非常缓慢。是更快的写一大块的数据一次硬盘然后编写大量的小块。缓冲区用于积累这些块。
