I assumed that both hdd as dvd were on the same controller, with dvd speed bottleneck within the reader itself and not the controller.
So I ran CrystalDiskMark speed test on my SSD drives and confirmed they are equal in speed. On the left the SSD that replaced the HDD and on the right the SSD that replaced the DVD:
For comparison these are the benchmark results of the RAID0 on the M2 sticks. The real advantage of RAID0 here is that write speeds are doubled and match read speeds. Reading is limited by the controller capacity so no real gain here with RAID0 (sorry I have no benchmarks results to attach for non RAID speeds so you'll have to take my word on it).

I have given up on trying to create a RAID1 config and simply decided to make one big RAID0 volume. Here is the result of the speedtest:

Yep pretty much made your M.2 NVME drives useless running at less than half really a 1/3 of there potential. and any failure of any kind on any one of the drives you will lose everything unrecoverable. Your total drive size is controlled by the smallest drive and any backups will take forever.
If your happy good for you
