cMP 4,1 SMART-Werte Crucial MX300 525GB - FAILING

[Elebato]

Moin,

mein Startlaufwerk mit Mojave ist eine SSD Crucial MX300 525GB auf PCI-Karte. Die aktuellen SMART-Werte sehen anscheinend nicht sehr gut aus. Deute ich das richtig, dass ich die SSD schnellstmöglich tauschen sollte, weil sie kurz vor dem Ableben steht oder mache ich mir noch unnötig Sorgen? Siehe Screenshots.

Deute ich das richtig, dass ich die SSD schnellstmöglich tauschen sollte

Ja.

 

[Elebato]

Gut, dann werde ich das mal machen. Zum Glück habe ich letzte Woche erst zwei Crucial MX500 2TB im Angebot für 166,99 Euro das Stück gekauft.

Du hast bei den Werten noch nicht Worst erreicht.
Check vielleicht mal mit DriveDX, der erklärt auch die Werte.

 

[Elebato]

Das werde ich rein interessehalber auch noch machen, aber dass die SSD langsam den Geist aufgibt kann man schon aus den Werten ersehen, oder?

 

[oneOeight]

Meistens haben haben SSDs ja overprovisioning, um die defekten Stellen zu ersetzen.
Siehe z.B. Wert 180.
Ist ja auch nicht so tragisch wie bei HDD, wo die meist aufgrund mechanischer Defekte schnell vermehren.
An sich müsste man von der Menge der geschriebenen Daten absehen können, ob die jetzt komplett durch ist.

Eigentlich sagen die SMART Werte nicht, dass die hin ist.
10TB geschrieben.
Read/Write Speed bei Current Session scheint aber lahm.
Warning beim Reallocated Count, geht auch hoch, jetzt 69 vorher 60.
Kann aber noch 1800 ersetzen.

Denke mal der geht mit den ersetzten Blöcken Hand in Hand.
Wenn du ruhig schlafen willst, dann tausch halt aus. Kannst dann extern weiter für nicht so wichtige Daten verwenden.

Ich habe jetzt mal den Reallocated NAND Block Count beobachtet und der steigt kontinuierlich, gestern noch bei 69, heute schon bei 78. Ich werde die SSD die nächsten Tage tauschen, dann kann ich tatsächlich beruhigter schlafen.
