I just figured out that AMD RAID in X470 does not support NVME storage at all, sata only!
So, im going with windows software "volume mirroring", the topic can be considered closed.
Maybe someone will be interested in my results - i heard many opinions on windows raid, people saying thats in every configurations its a performance degradation.
In my case i gain read speed and lost equal on write speed
Single 970 EVO Plus does 3566 MB/s Read and 3291 MB/s Write (seq)
Two 970's in windows mirrored volume - 5383 MB/s Read and 1702 MB/s Write (+1817 Read and -1589 Write)
NVMe's seems fine in this configuration, samsung software shows that TRIM is enabled on both devices
dedus got a reaction from Sawtaytoes in RAID1 windows vs chipset
