Even though SSD writes are faster than traditional disk writes, disk write cache typically provides good disk write performance and levels the playing field between the two types.
即便SSD写操作要快于传统的磁盘,但是磁盘写缓存通常提供良好的磁盘写性能,从而使这两种类型的磁盘可以实现相差无几的写性能。
Under normal circumstances, a write request is written directly to cache and incurs no delay because physical disk access is not required.
在正常的环境中,一个写请求是直接写入到缓存中而不会引起延迟的,因为它不需要访问物理磁盘。
Utilize disk storage with fast write cache for the logs.
为日志分配一个具有快速写入缓存的磁盘存储器。
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.
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。
Linux, under normal circumstances, USES a system file cache to buffer, read, and write requests from disk.
在一般情况下,Linux使用一个文件系统缓存为磁盘请求进行缓冲和读写。
After each write test, the test disk was unmounted as a way to ensure that no operations remained in Linux's disk cache.
在每个写测试之后,测试磁盘被卸载,以确保在Linux的磁盘缓存中没有操作。
This means the write-behind cache must reliably keep the data in the cache until it can be written to disk.
这意味着写入后缓存必须可靠地在缓存中保存数据,直到写入磁盘位置。
So the file system cache can help there quite a bit to avoid read and write operations on the disk.
所以文件系统缓存可以很大程度上帮助避免对磁盘的读写操作。
In a write-through cache, the data is written to the cache and to the disk before returning to the writing process to continue.
在write - throughcache模式下,在返回到写入流程并继续之前,数据将写入到缓存然后再写到磁盘。
