将磁盘写入延迟到比较适宜的时间可能会大大改善应用程序的吞吐量，但是，需要采用不损害数据完整性的方式执行。
Deferring disk writes to a more opportune time can greatly improve application throughput, but it needs to be done in a manner that doesn't compromise data integrity.

我们选择初始大小8GB，因为这个数量比较小，便于管理，也不会导致过分浪费磁盘空间。
We chose an initial size of 8 GB because it is small enough to be manageable but not overly large to cause wasted disk space.
尽管复制磁盘的思想从概念上来说是很简单的(开发也相对比较容易)，但是一个健壮的实现也有很多固有的复杂性。
Although the idea of a replicated disk is conceptually simple (and its development relatively straightforward), there are inherent complexities in a robust implementation.
这些磁盘删除了在旋转磁盘中的一些比较大的延时，因此其提供了一种维护与CPU 之间的数据流的方式。
These disks remove some of the large latencies found in spinning disks and therefore provide a way to maintain data flow to and from the CPU.
该脚本之所以要花费那么多时间，是因为它实际上要将整个二进制文件的副本导出到本地磁盘，以进行比较。
The script takes so much time because it actually involves exporting a full copy of the binary to the local disk for comparison.
如果磁盘在大小或速度方面有差异，可以通过设置卷尽可能利用磁盘的特性，比如把不经常访问的数据放在比较慢的物理磁盘上。
If the disks vary in size or speed, you can place volumes to take best advantage of the disks' characteristics, such as putting seldom-accessed data on a slower physical disk.
这种磁盘分配方法复杂性增加了，但好处是比较灵活。
This approach to disk allocation adds complexity, but the benefit is flexibility.
比较高的值表明磁盘非常忙。
事实上，硬盘注释考虑大量参数比如磁盘类型和数目，分区类型，等等，RAID设备相比较就非常简单。
In fact, compared to hard disk notation, which takes into consideration a lot of parameters like disk type and number, partition type, etc, RAID devices are fairly simple.
比较新的日志文件系统简化了系统重新启动时的磁盘检查过程。
Newer journaling file systems simplify the disk-check process when the system starts up again.
尽量加大ram，如果磁盘空间比较勉强，可以考虑添加一个新磁盘。
Dedicate as much RAM as possible, and if disk space is an issue, consider adding a new disk.
了解每个对象和整体数据库的增长趋势总是比较好，可以帮助您提前计划磁盘空间需求和数据库调优。
It's always good to know the growth trend of each object and the overall database to help you plan ahead for disk space requirements and database tuning.
如您所想，磁盘上的配置比较有趣。
The on-disk configuration is, as you might expect, a little interesting.
是否能够把不经常使用的文件存储在比较慢的物理磁盘上。
Can you isolate seldom-used files for storage on slower physical disks?
如果您打算从LVM或RAID磁盘引导，也需要拥有比较新的GRUB 或LILO版本。
You will also need a fairly recent version of either GRUB or LILO if you plan to boot from an LVM or RAID disk.
AmazonSimpleDB存储较小型的数据单元，使用比较低密度的磁盘，为数据访问速度而优化。
Amazon SimpleDB stores smaller bits of data and USES less dense drives that are optimized for data access speed.
在一台比较老的只有64MB内存的Windows 98Pentiumii膝上型电脑上创建100,000个轻便线程是轻而易举的(如果达到了一百万个线程，就会出现长时间的磁盘“猛转”)。
Creating 100,000 weightless threads is no problem on an older Windows 98 Pentium II laptop with only 64 MB of memory (at one million threads, long disk churning occurs).
“保存并继续”以在继续比较之前将您的更改保存到磁盘。
Save and continue to save your changes to the disk before you continue with the compare.
与磁盘比较，磁带更便宜，并且能保存更多数据，但是随机访问非常慢。
Compared to a disk, a tape is less expensive and holds more data, but random access is much slower.
