Bonjour à tous !
Quelqu'un pourrait-il me dire pourquoi mon ordi HP core i3 prend 6 min 30 s pour effacer un fichier de 700 mo sur mon disque dur interne avec la commande " shred -fuv ", alors qu'il ne lui faut que 30 secondes pour la même opération sur un fichier comparable situé sur un disque dur externe raccordé en USB 3.0 ?
Il lui faut aussi plusieurs minutes pour copier un fichier semblable vers une clé USB 2.0, alors que sur un " vieil " ordi amd 2 cœurs avec linux mint le transfert est 3 fois plus rapide !!
Merci pour vos lumières !
