btrfs RAID0 - should I stripe or duplicate metadata?

I want to use btrfs with raid0 on three nvme drives. These should contain the operating system and most application files, whereas valuable user files will be on a network drive or seperate disk. What is there any point in duplicating metadata with mkfs.btrfs -m if I am going to stripe the actual data? If one of the drives fails, everything will be lost anyway right? on the other hand, should I expect a performance impact either way? I am aiming for maximum throughput for my non-essential data I am actively working on.
