I have a Kingston RBUSNS4180S3256GJ SSD, which is an m.2 SATA SSD Kingston provides to system builders (see https://media.kingston.com/pdfs/emmc/MKF-815_design-in_SSD_lr.pdf).
This SSD appears to use a Phison controller like many other Kingston SSDs, as the SMART attributes correctly match (plus some vendors that are selling MKF-815 SSDs list them as having a Phison controller). I verified several SMART attributes as well and they appear correct (e.g., read Lifetime_Reads_GiB, Temperature_Celcius, etc.)
This change to drivedb.h appears to properly enable support for this drive (and likely this family):

I've attached the output of "smartctl -x" for this drive to this ticket as well.
