在群集中的主机控制器上使用回写高速缓存会影响性能。
Write-back caching cannot be used on host controllers in a cluster without hindering performance.
通常认为写高速缓存是个非常好的事物(请阅读参考资料中Linus对写高速缓存的解释和看法)。
The write cache is generally considered to be a very good thing (read Linus' explanation and opinion of write caching in Resources).
一些新式膝上电脑的硬盘有一个更令人讨厌的习惯：每当重新引导或暂挂系统，就丢弃它们的写高速缓存。
Some modern laptop hard drives have an even nastier habit of throwing away their write cache whenever the system is rebooted or suspended.
您可能不知道，但大多数新式硬盘有一个称为“写高速缓存”的东西，硬盘使用它来收集暂时被挂起的写操作。
You may not know this, but most modern hard drives have something called a "write cache", used by the hard drive to collect pending write operations.
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.
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.
一个高速缓存系统，当然不必过于复杂，但我一直相信，你经常能写出最好的代码，你可以写的最简单的代码。
A caching system certainly doesn't have to be overly complex, but I've always been of the opinion that very often the best code you can write is the simplest code you can write.
