由于这些进程产生了大量数据，所以允许将所有这些写操作都发生在闪存是不可取的。

Since a huge amount of data is produced by these processes, it is not advisable to allow all of these writes to happen to flash.

但有得必有失，例如闪存和硬盘存储数据的方式完全不同，所以运行一些视频处理软件等大程序时就需要一个软件工作区。

But there are tradeoffs too. For instance, flash handles data differently than a hard drives does, so software workarounds are needed for heavy-duty tasks like video editing.

这些数据更关乎容量，而不是IOPS，而通过闪存获取容量的代价颇为不菲。

These data are capacity bound rather than IOPS bound and flash is an expensive way to get capacity.
