USB 3.0 lecture 100mo/s ecriture 30 à 20mo/s ???!!!

Bonjour tout le monde , çà fait longtemps que je ne suis pas venu ici
... vu qu'ubuntu est de plus en plus simple et efficace!

cependant j'ai un soucis sur notre nouvel ordi ( un très sympatique petit tout en un Lenovo C365 ) acheté il y'a quelques jours.
http://www.ldlc.com/fiche/PB00173610.html  (je ferais sûrement un compte rendu de ce matos pour la communauté!)

Mise a part un tuner tnt usb que j'ai pas encore réussi à configurer (pas eu le temp), tout marche parfaitement sous ubuntu 14.04 (64 bits) sauf les deux port usb 3.0 qui semblent fonctionné seulement dans le sens de la copie du disque dur usb 3.0 vers l'ordi ..et non l'inverse. c'est un WD My passport Ultra 1 To USB 3.0 quasi neuf et vide à 80% .
test effectué avec un fichier video de 5.4go

Sous le Windows 8.1 vendu (racketté) avec le pc,  ce WD 1To tourne entre 100 et 80mo/s dans les deux sens. Pas immédiatement au premier branchement mais après que w8.1 ai automatiquement installé le disque dur en question. Probablement un bidule ou driver spécifique installé automatiquement depuis le www puisqu'il n'y a plus rien sur le hdd que j'ai formaté en NTFS puisque c'est surtout pour lire les film sur la tv du salon... un bon débit usb 3.0 est bien le seul avantage que j'ai trouvé à w8.1 ! troll inside ! lol

En tout cas ça me semble donc pas un soucis du hdd
nb:  j'ai rien d'autre pour tester en usb 3.0 ...zut!

lsusb semble voir le hdd mais précise pas si c'est en USB 2.0 ou 3.0

cet ordi comporte 4 port usb 2.0  (sur lesquels sont branché mon tuner tnt usb, ainsi que les clavier et souris filaire , surement les usb1.1 qu'on apperçoit)  et 2 port usb 3.0 , un libre (Bus 006 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub ??)    et le second occupé par le HDD 1To  ( Bus 005 Device 002: ID 1058:0741 Western Digital Technologies, Inc. )

j'ai tenté la manip sur cette page http://forum.ubuntu-fr.org/viewtopic.php?id=515611

sudo gedit /etc/default/grub

remplacez la ligne GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" par celle ci :

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi"

faites un

sudo update-grub

Redémarrez votre machine, et c'est bon !

aucun changement ! puis   j'ai tenté en rajoutant l'option "noaer" à la fin  comme vu là => http://ubuntuforums.org/showthread.php?t=1680278

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi,noaer"

mais là par contre c'était pire ,  35mo en lecture  20 mo en ecriture

bref j'ai remis le "quiet splash"  tel que d'origine et me revoilà sur le forum après avoir rebooter

Maintenant je m'en remet à vos conseils .
Merci d'avance :-)

en complement  le dmesg (un peu long tout ça et j'ai l'impression qu'il me manque le début )

voici la partie qui me semble intéréssante

Re : USB 3.0 lecture 100mo/s ecriture 30 à 20mo/s ???!!!

Bonjour,

... le hdd que j'ai formaté en NTFS puisque c'est surtout pour lire les film ...

Pour lire, je crois que tout est dit.
NTFS est un format étranger à Linux, rien d'étonnant que sa gestion ne soit pas immédiate.

Re : USB 3.0 lecture 100mo/s ecriture 30 à 20mo/s ???!!!

Bonjou.
Je confirme que ubuntu ne fait pas des merveilles lorsqu'il décide d'écrire sur du NTFS.
Toi-même tu as constaté  que la première fois windows n'est pas terrible.
              Tu dis que tu viens de formater le disque, En fait pour que windows formate  très rapidement le disque (à partir de windows 8). Le disque est simplement marqué "à formater" et le  formatage se fait au fur et à mesure des besoins.   Il est possible que ubuntu ne soit pas super efficace dans cette première étape .
Tu pourrais renouveler le test dans quelques jours au besoin avec le logiciel "smartctl" qui a une fonction de test de performance d'écriture.

Re : USB 3.0 lecture 100mo/s ecriture 30 à 20mo/s ???!!!

Si tu veux faire des tests d'écriture de ta clé sous Linux il faut respecter plusieurs conditions pour ne pas être bridé en vitesse :

1 - Utiliser des formats de système de fichier natif a Linux c'est a dire par exemple formaté ta clé en EXT4 (pas NTFS cela fausse les résultats !)

2 - Si t'a clé est USB3.0, ton port USB doit aussi gérer cette norme sinon elle sera bridé en vitesse

3 - Le pilote USB3.0 doit être installé ce qui est le cas par défaut sous ta distribution mais pas forcément sous certaine version de Windows par exemple.

4 - La vitesse de lecture du support source (c'est a dire a partir de quel endroit tu copie les fichiers) doit être supérieur (ou au moins égal) a la vitesse d'écriture maximum possible du support destination (a savoir la clé).

5 - Les clés ne sont pas toute de la même qualité, il peux y avoir des différence de débit non négligeable entre différente clé USB3.0.

6 - Enfin il faut savoir que la vitesse d'écriture est toujours inférieur a la vitesse de lecture pour un même support.

Mais a première vu tu es bien en USB3 car ta vitesse de lecture de ta clé est trop rapide pour de l'USB2.

Rappel débit maximum de l'USB2 de lecture : 480 Mb/s soit 60 Mo/s et ça c'est le débit théorique, en réalité les chiffres sont toujours inférieur (vers 40/45 Mo/s) donc tu es en USB3 puisque tu fais du 100 Mo/s...
