Unrealistisch große Werte in SMART

Unrealistisch große Werte in SMART

Vor kurzem hat mir Ubuntu mitgeteilt, dass meine SSD dem Untergang geweiht ist. Dieser Computer läuft seit etwa 10 Jahren, davon etwa 4 Jahre mit dieser SSD. Diese Meldung erschien nach dem Aufwachen aus dem Standby-Modus.

Smartctl sagt Folgendes:

Wie Sie sehen, sollte meine SSD 821 Jahre lang funktionieren, 159 Zebibyte speichern (mit einer Geschwindigkeit von 6762 GB/s) und ungefähr hundert Mal den Geist aufgeben. Allerdings funktioniert alles einwandfrei und das auch nur seit ungefähr 4 Jahren.

Warum ist das so und was soll ich tun?

UPD: Tatsächlich starb es mehrere Tage später.

UPD2: Es ist einige Tage später wieder auferstanden und fühlt sich wie neugeboren an.
