Linux disk is SSD or HDD

    How to determine if Linux disk is SSD or HDD :

     

    Linux automatically detects SSD, and since kernel version 2.6.29, you may verify sda with:

    cat /sys/block/sda/queue/rotational

    You should get 1 for hard disks and 0 for a SSD. In my case, I get 0 (cause it’s a SSD).

    server:~# cat /sys/block/sdb/queue/rotational
    0
