What kind of attributes did you find relevant? I imagine the 19x codes…
I’ve read the Blackblaze statistics and I’m using a tool (Scrutiny) that takes those stats into account for computing failure probability, but at the end of the day the most reliable tell is when a drive gets kicked out of an array (and/or can’t pass the long smart test anymore).
Meanwhile, I have drives with “lesser” attributes sitting on warning values (like command timeout) and ofc I monitor them and have good drives on standby, but they still seem to chug along fine for now.
