1. I am not recognizing the drive. However, I would strongly recommend against QLC due to performance and reliability issues. You would be much better served by TLC or better yet MLC drives.
2. The motherboard can take two drives. It also supports on-board hardware RAID. I would strongly suggest getting two identical drives, and putting them into a hardware RAID-1 array for redundancy (remember: redundancy is not backup). This will also alleviate some of the aforementioned QLC issues, allowing you to run QLC drives more safely.
