FileUtils.highIODevice介绍

[英]Attempts to discern if the given path is mounted on a device that can likely sustain a very high IO throughput.

A high IO device is expected to have negligible seek time, if any, and be able to service multiple IO requests in parallel.
[中]尝试识别给定路径是否安装在可能维持非常高IO吞吐量的设备上。
高IO设备的寻道时间可以忽略不计（如果有的话），并且能够并行处理多个IO请求。
