Place I work got hit HARD by this. Year and half before I started at this company they setup 4 SSD's in a RAID 5 config.
One day while working on things I noticed a message on our server indicating a PDR1001 Error (Predictive Failure). So we ordered a new one. The new SSD arrived. We popped in the new one and the RAID started to rebuild.... Lo and behold during that operation Drive 1 threw the same error and the whole thing came crashing down...
We ended up losing the whole array. I had NO idea we had SSD's in the system. I had no idea that no one was monitoring their life.... The moment I saw we had this issue I saw the writing on the wall. 4 SSD's in a raid 5 all installed at the same time... means all SSDs end up with the same approximate critical end of life.
All I could do was shake my head at the whole thing... Pretty sure those in the charge who setup the array still don't understand why this situation was 100% avoidable...
