rcraid - I don’t understand Your point, I see on github Linux driver, people do report that it works for them on earlier AMD boards, so to me it’s supported by Linux.
Doesn’t matter what You think of dual boot, it do works for me and if my host OS crashes for whatever reason I can still work booting into other system. And now because I don’t see that RAID in Linux portion of data is not accessible from Linux so that’s a problems for me.
I came from x299 platforms and as much as I hate to admit moving to AMD HEDT is disappointment. SATA performs worse, not deal breaker but still, ASUS mobo are crap for any audio work as SPDIF doesn’t work (confirmed on 2 SKU, 3 different boards, at least by 2 users, I’m one of them), and now that RAID issue. Only strong point is CPU performance for MT workload with is great, rest mediocre at best considering price point of this platform.
