Question NEWBIE AMD Ryzen 9 9900X System build questions

[KLund1]

Hi,
I'm a AMD newbie. I've built intel systems since the 90's. My last amd build was a K2 cpu.
The new intel chips are not going to do it for me. The R9 9900x looks about right for me. I'm not big gamer, but some. I edit personal video, & music. Database stuff. Program cross compiling, mostly general computing.
What I really like is fast SDD NMVE M,2 access, fast boot, fast program/data load, and saves. I will be running a raid 0 setup. Yes I have a very robust backup system. I've been using raid 0 for years on my main rig.
So I want a motherboard that can do raid 0 in PCIe 5, but not cut into the bandwidth of the CPU or the nvidia 3090 I'm going to use.
I'll need at least 6 sata ports for spin rust I still use. These do not need to be super fast, but usable. These should not cut into the raid 0 setup, as I will be moving data between HDD and the raid 0 drives
I have no clue about amd ram but I want something to is fast and has something like the intel's XMP. I'm thinking 32gb ram. Is 4x8Gb sticks or 2x16gb sticks better in amd land?
I'm not an RGB fan so don't worry about looks, except I don't like white mobo's. I'm partial to Assus boards, but am will to change if there are better options for my needs. Oh I'll need a new PSU for all this. What wattage?
All this will going in a mid-tower case I have.
Any advice and suggestions would be most welcome.
Thanks

Raid on a M.2 drive is a big no, sounds good but can actually hurt performance.
High quality 1K /1200 watt PSU.
A set of 2X16gb or 2X 24gb if you need more than 32GB.
Good CPU cooler that CPU under load pulls in the 170watt area.

Thanks for the quick reply
Understood.
Raid 0 on one drive, yes, is useless.
I would be using 2 (two) nvme m.2 drive sticks on the mobo in stripped raid 0. I probably should have more clear above. Sorry
I assume these should go through the same controller on the board to reduce latency?
Is there something about nvme m.2 standard that slows performance with 2 or more physical drives?

Yes I know you were saying raid on 2 drives still a big no no..
It's great for just running benchmarks but not for real world performance.

Do you have any links explaining this a little further?
I am running raid 0 on my main rig but I built it about 7 years ago. (that is why I want to upgrade)
Back then, I tested speed with win 10 installed in single drive nvme m.2 128Gb drive for about a week. then built the raid 0 with 2 drives and saw a majorly huge improvement in speed in my general usage. Boots, program loads, data saves all were much faster. So I kept the raid 0 going all these years.
Have things changed that much over time?
