Same question. On the Z270 version of Chi it says they are AURA, plain and simple (unless ASRock AURA RGB LED is different from Asus Aura). But AM4 version is ASRock RGB LED, whatever that means...
Also, if I run 2xM2 in raid 0/1 on this one I assume it will slow the top Ultra slot down to 20?
PS. Just noticed the Z270 has 3xM.2 @ Ultra. So basically 10/10 in the AM4 world is like a 7.5/10 in the Z270 world. Ok...
As cadaveca has said earlier: "My scores don't necessarily reflect how one board performs vs any other, either."
So on one hand, X370 Taichi has a lot of very useful features, is well designed, looks OK and so on. It's hard to find a fault, if you're just looking at this single board - hence the perfect score (and the word "perfect" all over the text).
But there clearly are some more appealing motherboards out there: with better cooling, better OC abilities, better disk performance, better fps in games, better power consumption, better circuits etc.
And even if they're all for Intel CPUs, should it not be taken into account? AM4 is a new platform and more polished stuff is coming soon. How will it be rated if we got a "perfect AM4 board" a month after release?
And if the score doesn't reflect how a device "performs vs any other", why compare at all in the review? Why is there a "sort by rating" option on TPU?

So is this ASRock better than ASUS Maximus VIII? Is it not? Why?
If scores shouldn't be compared, why are they so precise? Why not a simple 5-star system?
Giving a 10.0 was a big risk. Like you, I was instantly pushed back by the poor M.2 situation. In the Kaby Lake generation, a 2x 32 Gbit/s in ATX boards got fairly pedestrian - it's seen in many mid-range models.
But then again: this is cadaveca's approach and he can evaluate according to his views and knowledge. That's the whole point of being a reviewer.
Other than the final score, the review itself is pretty good.
