Ce rapport SMART est très instructif.
Il montre un modèle répandu de disque rotatif, le
Seagate Barracuda 500 Go, 7.200 tours/minute
et qui jouit d'une réputation plutôt bonne, et qui cependant, est devenu inutilisable à 10.595 heures.
Le plateau est en parfait état :
197 Current_Pending_Sector 0x0012 100 100 000 0
198 Offline_Uncorrectable 0x0010 100 100 000 0
Et le micrologiciel n'a même pas trouvé de secteur méritant d'être réalloué (vers un secteur de secours) :
5 Reallocated_Sector_Ct 0x0033 100 100 036 0
.
Alors d'où vient cette usure prématurée de l'électronique ?
Qu'est-ce qui use l'électronique ?
Ce sont principalement les surtensions. Et elles surviennent à
chaque allumage et à
chaque extinction.
Donc éteindre un pc ou un SSD ou un HDD nuit à leur longévité.
Ici on voit des
sessions très courtes (90 minutes).
En effet ce disque a connu
7061 mises sous tension et
7863 mises en rotation, soit par mise sous tension, soit par sortie de "sleep mode".
[Pour les spécialistes : oui, il semble bien que les attributs 4 et 9 soient ici inversés
Cette inversion est fréquente, donc à garder en mémoire.]
10595 heures / 7061 = 1,5 heures = 90 min.
En prime,
Qu'est-ce qui use la mécanique des disques rotatifs (HDD) ?
Ce sont les mises en rotation. Surtout à froid !
Conclusions
/![/b] Pour la longévité de votre matériel, évitez de l'éteindre !
Pour la longévité de vos HDD, désactivez leur mise en veille !
