Cache drive failing, or is it?

Featured Replies

For the last few days I have been getting errors from my unRAID server like the following:

Event: unRAID Cache disk SMART health [1]

Subject: Warning [HOYLAKE] - raw read error rate (failing now) is 34213

Description: ST240HM000_Z4N0013X (sdc)

Importance: warning

But I ran an extended SMART test where the result is "SMART overall-health self-assessment test result: PASSED"

 

How can it have Passed with a read error rate that is failing?

 

Should I replace my cache drive?  It is a Segate 240GB SSD.  It has been in continuous use since I built this server a little over 2.5 years ago.

 

Here is the full SMART text file:

I would still replace it when possible, if nothing else it will likely be performing worse than normal.
