For this particular SSD with the listed SMART fields, I would THINK about panicking when any of the following increases (Real, Raw, or Current value; they’re all currently at 0):
-retired block count
-program fail block count
-erase fail block count
-program fail count
-erase fail count
-reallocation event count
And to kinda gauge where the drive is overall, look at the “Current” value for SSD life left. It’s currently at 92, which is well above the threshold (10). If you find the value decreases in a large chunk, you’ll likely find a bunch of write errors have occurred (programming or erasing). Otherwise, the drive should be fine for some time. Of course, backups are always suggested.
If I’m reading it right, it looks like you’ve written (& read) more than 30 TB over the life of the drive. Does that estimate sound about right?
Depending on the Kingston drive model it is, 30 TB might be about half the rated write amount for the entire drive. If that’s the correct amount of writes your drive has encountered, the drive is fairly okay at keeping the wear & tear level across the drive, so it shouldn’t be a problem for around 1.5 to two years assuming linear progression. (Conservative estimate, as the drive is the OS drive, and some of the NAND will be rewritten fewer times due to OS files rarely being rewritten compared to some other types of files).
