Confession: I chose the renewed 512GB NVMe to save money for a better GPU. After a month I ran a SMART check because a friend told me to.

Disk health
S.M.A.R.T. status: BAD
Reallocated sectors count: 1,872 (threshold exceeded)
Back up your data and replace the disk as soon as possible.
The Percentage Used line is yellow. The seller says refurbished drives are fully tested. I am now wondering what exactly they tested xD Is this a normal state for a second hand SSD or a warning that it is near the end?
