SOLVED Device: /dev/ada3, Failed SMART usage Attribute: 194 Temperature_Celsius. (Crucial BX500 240GB)

[BloodyBonkers]

I ran a burn in script on the new ssd intended as a boot drive for my grandparents future FreeNAS box ;) using this script from github "Spearfoot/disk-burnin-and-testing".

What I ended up with after the script completed was an alert from freenas giving me this message: "Device: /dev/ada3, Failed SMART usage Attribute: 194 Temperature_Celsius."

Reading from the smart data the highest reported temperature was 62c, and the specified operating temperature range listed by crucial is 0-70c.
Seeing as the temperature was within that range, why did I get an alert?

Should I be worried and think about replacing it, or can I start using the ssd and expect it to work fine.

Here's the output from smartctl -a /dev/ada3:

It's a problem with those SSDs, they are using a wrong SMART temp threshold.
