Are you sure SSD is that slow? NVMe devices are so fast that I hardly believe there's any need for RAID 0.
In AWS iirc NVMe max out at 2GB/s - I'm not sure why that's the case. I know there were issues with the PCIe controller in the past being the bottleneck, but I suspect there's something more to it than that.
