I understand the problems/failures that can happen but im just wondering if Im able to put 2 m.2 ssds in raid 0 on this motherboard.I would strongly advise against a RAID0 with M.2 NVME SSDs. You're just inviting problems down the road. I've seen it several times now, even here in this forum.
You should get one NVME SSD, but a fast one, such as the 970 Evo Plus or 970 Pro. This will remove the storage bottleneck, the CPU won't really have to wait much anymore for the SSD. You have high enough data rates and high enough IOPS.
If you create a RAID0 now, you're introducing several more failure points or potential problems, without it actually doing much for real-world speed aside from theoretical benchmarks.
