You did a good troubleshot!
In my opinion can be a bad SSD, maybe one of the 2 layers is having some issue or the SSD controller.(if i remember correctly, you have a double layer SSD with an integrated controller that can enable RAID array).
Maybe you can try to destroy the RAID array and check with diskpart or scandisk the single layers for errors.
