The SLC cache is managed by the controller, it's not going to forget to write it to the flash cells being managed as TLC/QLC, the controller is transparently storing your data in both. The controller knows if put some data in the SLC cache and some data in the QLC, and that that data needs to move from SLC to QLC, and that that other data in the SLC was marked deleted so now it can return that entire block to being addressed as QLC. I don't know. I'm just trying to say that since flash isn't volatile the SLC cache isn't treated as volatile cache either.
