Saya ingin tahu apakah disk adalah solid-state drive atau hard disk.
lshw
tidak terpasang. Saya lakukan yum install lshw
dan dikatakan tidak ada paket bernama lshw. Saya tidak tahu versi http://pkgs.repoforge.org/lshw/ mana yang cocok untuk CentOS saya.
Saya mencari di internet dan tidak ada yang menjelaskan bagaimana cara mengetahui apakah drive itu SSD atau HDD. Haruskah saya memformatnya terlebih dahulu?
Hasil dari fdisk -l
