@RAZVAN Welcome to the Win-Raid Forum!
As far as I know the Company SK Hynix has never released an own driver for their NVMe Controllers. For details please look into >these< posts.
On the other hand it will not be a problem to get the SK Hynix NVMe Controller properly working. You can find the best driver for your specific hardware configuration yourself.
According to my own experience these are very good options:
a) Microsoft’s generic Win10/11 in-box NVMe driver
b) Phison’s generic NVMe driver v1.5.0.0 WHQL
c) Micron’s NVMe driver v2.1.19.0 WHQL (installation has to be forced by pressing the “Have Disk” button)
d) Samsung’s NVMe driver v3.3.0.2003 WHQL (installation has to be forced as above mentioned)
Good luck!
