如何使用C语言确定存储类型(SSD驱动器或HHD机械驱动器) [英] How to determine storage type (SSD drive or HHD .mechanical drive), using C language

问题描述

如何从C程序读取驱动器的硬件信息? (即确定驱动器是SSD还是机械磁盘.)

How can I, from a C program, read the hardware information of a drive? (I.e. to determine if the drive is an SSD or a mechanical disk.)

推荐答案

SSD应该将自己标识为非旋转.以linux为例，您可以通过sysfs获取信息:

SSD are supposed to identify themselves as non-rotative. For linux, as example, you can get the info via sysfs:

cat /sys/block/sda/queue/rotational

如果返回0，则说明您有SSD ...

If it returns 0, you have SSD...
