*Title says it all
Tried googling some numbers but didn't really find anything solid.
It's almost like everyone just forgot about RAID.

With today's state of HW/SW/OS RAID, how are the following compared?
1. 2TB high-end NVME VS 2x1TB (RAID0) budget NVME --- cost about the same, if not less
2. 2TB high-end NVME VS 2x1TB (RAID0) high-end NVME --- should be faster and costs more, but how much faster?
3. PCIe 4.0 NVME VS the above

The goal here is not to achieve redundancy of boot+game drive, but either to have 2TB storage in 1+1 RAID0 that's either faster or cheaper than a single 2TB storage.
Cost of equipment that enable 2x NVME slots (if not supported by mobo), should be added to the comparison data.

Let me know your thoughts.
Cheers

PS: If I still had my disposable income, I'd probably run the tests myself.

I don't think more bandwidth would make a noticeable difference, coming from PCIe 3.0. But yeah, two PCIe 3.0 SSDs in RAID0 should give you about the same bandwidth as a PCIe 4.0 SSD, while being significantly cheaper. But only if both SSDs are really connected to PCIe 3.0/4.0 x4 connections, so you'd need an x570 motherboard when going with AMD's AM4 platform. And chipset PCIe lanes share a common connection, which can also limit your bandwidth.
To install Windows on RAID 0 a solution like AMD-RAID or Intel RST RAID would be a possible solution, but you might need to manually load drivers so the Windows installer can support the RAID volume provided by your motherboard.
I wonder if it's also possible to install Windows on a striped dynamic disk volume, probably not.
Hardware RAID solutions for Nvme drives exist, but they would cost you a couple hundred dollars, and you'd also need to get U.2 to M.2 adapters.

it will be faster but not cheaper, a single reliable 2tb nvme is going to be better for two reasons (or 3), expansion is easier, cost is less, and reliability will be twice as good. i have been in the same boat eyeing 2tb nvme drives. instead i just purchased a second 970 evo plus 1tb for my desktop (forget how much 120?) and i have two 1tb 970 evo plus in raid0 on a laptop (only because it came that way) with a 1tb pcie sata for extra storage and it is Very fast and fun to use but i don't really notice much difference except for not having to install to different locations.

if its just for games and boot drive i wouldnt worry about speed.

On the flip side, I really don't see a difference with RAID0 PCIE 4 NVMes on my 3970X system compared to the 970 Evo Plus on my 9900K and 10700K builds.

Thanks for the feedbacks

I'm leaning to go with a single drive, after some rough calculations.
I've a 1TB 970 Evo Plus, but even with that, the added cost from the mobo offset things quite far - personally, I'd rather spend the $ on storage, not on mobo
Cost V Performance ratio has changed significantly compared to my last build, raid0 now feels like indulgence/luxury :)
