【Linux】Linux下判断磁盘是SSD还是HDD的几种方法

Posted 2023-03-22

参考技术A You should get 1 for hard disks and 0 for a SSD.

It will probably not work if your disk is a logical device emulated by hardware (like a RAID controller).

通过判断cat /sys/block/*/queue/rotational的返回值（其中*为你的硬盘设备名称，例如sda等等），如果返回1则表示磁盘可旋转，那么就是HDD了；反之，如果返回0，则表示磁盘不可以旋转，那么就有可能是SSD了。

使用lsblk命令进行判断，参数-d表示显示设备名称，参数-o表示仅显示特定的列。
