Post by pehacheOu vois-tu la quantité de données écrites ? Dans les rapports SMART ?
Par exemple. C'est sans doute LA donnée importante, avec l'état de santé
(un mot, un pourcentage), pour un SSD. Je la lis dans CrystalDiskInfo ou
dans Samsung Magician, écrit en gros.
Je suis sur Mac, ces softs ne tournent pas dessus. Mon SSD est un
Crucial, et voilà ci-dessous le rapport SMART que j'obtiens sur ce
disque. J'ai du mal à trouver/interpréter dedans les infos pertinentes
pour le SSD :
$ smartctl -a /dev/disk1s2
