另外，通常需要高速磁盘或数据库(或二者)，以增加缓存大小，或获取高可用性。
Additionally, high-speed disks or databases (or both) are typically required to increase the size of the cache, or for high availability.
通过将暂挂的写操作放到高速缓存中，硬盘固件就可以重新为它们排序，并为它们分组，以便用尽可能最快的方式将它们写到磁盘中。
By putting pending writes into a cache, the hard drive firmware can then reorder and group them so that they're written to disk in the fastest possible way.
为了解决这个问题，把系统放在快速写入高速缓存磁盘上，以减少磁盘写入时间。
To address this, the logs are placed on fast write cached disks, reducing the disk write time.
如果该值为0，那么将不会创建磁盘高速缓存。
磁盘子系统将管理从高速缓存到磁盘的数据复制。
Copying the data from the cache to the disk will be managed by the disk subsystem.
还可以设置如果内存高速缓存已满，就将缓存转存到磁盘(通过磁盘转存功能)。
It can be configured to offload cache to disk if the memory cache is full (via the disk offload function).
不幸的是，现在市场上某些膝上电脑的硬盘具有这样一种不可靠的特性，即忽略将它们的写高速缓存刷新到磁盘上的所有正式AT A请求。
Unfortunately, certain laptop hard drives now on the market have the dubious feature of ignoring any official ATA request to flush their write cache to disk.
代理缓存采用了结合内存高速缓存和基于磁盘的缓存，以节省大量的数据几乎没有开销。
The proxy cache uses a combination of a memory cache and a disk-based cache to save large amounts of data with little overhead.
磁盘高速缓存目录XX不存在。请在首选项框中输入一个新的目录。
Disk cache directory XX does not exist. Please enter a new directory in the preferences box.
图像从磁盘高速缓存获得。
高速缓存中包含脏数据，但由于某些虚拟磁盘丢失或将转为脱机，因此无法将高速缓存的数据写入磁盘。
The cache contains dirty data, but some virtual disks are missing or will go offline, so the cached data can not be written to disk.
增加内存可以直接提高系统的性能，因为直接访问物理内存比访问存储在磁盘上的高速缓存要快得多。
By increasing the RAM storage, you directly increase the performance of the system, because direct accesses to physical memory work much faster than accesses to disk-stored caches.
通常，应该在磁盘上规划几千兆字节的高速缓存存储容量，内存至少应该有128MB，最好有几千兆。
Typically, plan for a cache storage capacity of several gigabytes on disk, as well as at least 128 MB of RAM, preferably gigabytes of RAM.
高速缓存服务器管理员都承认内存和磁盘存储是最重要的性能因素。
Cache server administrators recognize that RAM and disk storage are the most important performance factors.
个人计算机对经常调用的代码设置了存储器超高速缓存，大多数浏览器程序都有本地高速缓存，它在内存中或磁盘上存储最近浏览过的网页。
PCs have memory caches for code that's called often, and most browser programs have local caches that store recently surfed Web pages either in memory or on disk.
单一高速缓存服务器每次只能处理这么多请求，即使为机器增加内存、磁盘空间和处理器，目前也只能做到这一步。
A single cache server can handle only so many requests at a time, and even pumping up the machine with memory, disk space, and processors takes its capacity only so far.
