[SOLVED] Can't Setup NVMe Raid0 on Gigabyte GA-Z270X-UD3

I installed a 256GB NVMe drive in the slot next to the CPU. I put another one in a PCIe x16 Adapter.
Windows sees them fine, and they both show up in BIOS in the NVMe area.

The product page has:
" Dual NVMe PCIe SSDs in RAID 0 Support"
VERY misleading as I thought it meant it had two NVMe sockets.

Anyway, I cannot for the life of me figure out how to get the two in a RAID 0.
When I try to use EZ Setup in the BIOS is says it needs to enable RAID and reboot. It reboots, and does it again and again and again....
I do NOT want this as a boot drive, I have two 3.5" SSDs installed, one is the boot drive, and the other storage.

The recent manual has this:
" (Note 2) An M.2 PCIe SSD or an U.2 SSD cannot be used to set up a RAID set either with an M.2 SATA SSD or a SATA hard drive. "
I'm not entirely clear on what that says, that I can't use RAID if I use the M2 and PCIe M2 ?

I would greatly appreciate some help getting this to work, I don't really want to create a Striped Volume in Windows 🙁

your issue would seem to be the factor of you using a pcie m.2 with a sata m.2 it's telling you right there it won't run in RAID with a sata m.2 and pcie m.2

So they give you a M2 slot on the board that you can't use with anything else, and their claim of NVMe RAID is ONLY if you put in 2 adapters into 2 of the 3 PCIe slots? What a crock.
 
I had to update the BIOS to get the EZ Raid to work.
While I was able to get it to work, once I set it up I was no longer able to boot from my other drives.
UGH, such a mess!
 
Yeah, seeing a RAID0 without any very specific usage that requires constant transfers of very large, sequential files, is just odd. It's not even good for nerd cred; these days, having a RAID that you don't actually need is a little bit like buying pre-torn jeans or showing up at a skate park with the price tag still on your skateboard.

Very well put I like it hahaha

  1. What specific drives are these? Make/model, please.
  2. How are they connected?
  3. What other drives are in this system, and what is on them?
  4. RAID 0 + SSD is rarely a good idea.

  1. 256GB Samsung 970 EVO
  2. One is connected the the M2 slot on the motherboard. The other is connected via a NVMe PCIe x16 Adapter Card.
  3. 256GB Samsung 850 Pro (OS), 1TB Samsung 870 (Storage)
  4. I'm seeing that. At this point I think I can do without RAID 0, but I can't even get the system back to where it was before where all the drives were seen by Windows.

Well the PLAN was for this to be a large storage server, and I was going to use them to increase transfer speeds via PrimoCache.

Use of the M.2 port can disable one or more SATA ports. Causing the system to not see the OS drive (850 Pro) and not boot up.

Section 1-8 in the motherboard manual lays out the actual possibilities.

Yes, but before I tried to get the RAID working BIOS and Windows saw all the drives. I could boot from my 850 Pro, and it saw the two 970s as two additional drives. If I could get back to that point I'd be OK, but I can't, I'm totally stuck with booting to Windows with no NVMe drives, OR I can have the NVMe drives, but no windows.

RAID-0 on consumer motherboards work only in these 3 combinations:

  1. By using 2 SATA SSDs connected to 2 SATA ports.
  2. By using 2 M.2 SATA SSDs connected to 2 M.2 SATA capable ports.
  3. By using 2 M.2 NVMe SSDs inserted in 2 M.2 NVMe capable ports (if you do have those on your motherboard). They’ll run through the chipset.

Mention:
Trying to create a RAID configuration by using an M.2 NVMe SSD in an M.2 NVMe port, and the second M.2 NVMe SSD inserted through an add-in card into a PCIe slot doesn’t work!

It basically detect the pcie m.2 as a sata generally dosnt it? That's atleast what I was informed.

No, it detected both NVMe devices as PCIe. I COULD and DID successfully create a RAID volume. The problem is that Microsoft in all their wisdom makes it so Windows installed ONLY the AHCI drivers if a RAID volume isn't present at the time of install. Getting it to recognize a RAID volume after the fact is a freaking nightmare.

At this point, I don't want the damn RAID, I just want to be able to use my drives individually, but I can't figure out how to get back to that place.

Hello!

By looking at the specs of your motherboard, I’ve seen that you only have 1 M.2 M-22110 SATA/PCIe port.
So, you won’t be able to use 2 M.2 NVMe SSDs to create the RAID configuration.

For RAID, you’ll need to use 2 NVMe PCIe 3.0 interface drives, not M.2 PCIe!

And if you want the RAID config. to be bootable, you’ll need to use 2 PCIe 3.0 drives from Intel!

Like I said it generally not always some mobo designers do things differenet...

The reasoning behind this from multiple understanding is Intel is the only one that has designed their cards to read fully though pcie slots other company's just push them out for sale. Intel has been around for a long time and has learned some tricks along the way that others are still working on
