Plasma randomly warns that my SSD is going to die?

Yeah, I keep everything important backed up. I'm definitely fine if it dies. I'm just curious really.

This happened to me a few weeks ago and the pain is still fresh. Please tell us your data is safely backed up, OP.

Always have backups. "If you only have one, you have none".

It's a relatively recent 1TB Samsung 980.
