Petite mise à jour :
2068 jours (5 ans et 8 mois) que le SSD est installé sur le serveur LaFibre.infoAujourd'hui j'ai
-
Wear_Leveling_Count = 81Wear Leveling Count : Représente le nombre d’opérations moyenne d’effacement effectué sur le support (le nombre de fois qu’un bloc a été effacé). C'est une moyenne sur le nomre total de blocs du SSD et non un maximum.
-
Total_LBAs_Written = 30149638521Total LBAs Written (attribut SMART 241) : Représente la taille totale des blocs LBA (Logical Block Addressing) requis pour traiter l’ensemble des demandes d’écriture envoyées au SSD depuis l’hôte. Pour calculer la taille totale (en octets), il faut multiplier la valeur remontée par SMART par 512.
30149638521*512/1000000000 = 15436,6 Go écrit depuis 2068 jours, soit
7,465 Go par jour. Je suis loin de la limite pour la garantie : Le SSD est garanti pour 150 To écrit ou 10 ans. 150 To sur 10 ans = 150000 Go sur 3652 jours = 41,068 Go par jour.
