macos - Is my SSD dying?

I walked away from my late 2012 Retina Macbook Pro for about 10 minutes, and came back to a gray screen with a flashing folder with a question mark on it. I wasn't doing anything too disk intensive at the time. Disk is a 480 GiB OWC Aura Pro installed about a year ago.

smartctl -a disk0 gave the below output. Being that the device is not in the database (I ran update-smart-drivedb moments ago), I'm wondering if the data could be incorrect? Either way, the values of Raw_Read_Error_Rate, Reallocated_Sector_Ct, and Reported_Uncorrect have me a bit nervous.
