Pour le cpu j'ai regardé avec htop. Avec top le process smbd occupe 24% du cpu (voir image en PJ).
La commande hdparm -I ne correspond à aucune option, tu voulais savoir quoi exactement ? Pour le reste voici :
root@serveur:~# dd if=/dev/zero of=/data/test bs=1M count=1024
1024+0 enregistrements lus
1024+0 enregistrements écrits
1073741824 octets (1,1 GB) copiés, 7,73777 s, 139 MB/s
root@serveur:~#
Le disque est plein à 80% donc c'est à mon avis normal que le test d'écriture sois un peu limite.
