RAID 1 with M.2 SSDs

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I'm trying to set up RAID 1 across 2 M.2 SSDs. Right now, RAIDExpert2 doesn't find any disks and all the array options are ghosted out. Could you please tell me how to set up RAID 1 for a pair of M.2 SSDs?

Hardware:
X570 Taichi 
Ryzen 3600x
2 x Crucial MX500 M.2 2280SS plugged into M2_1 and M2_2

Setup:
Advanced > Storage > SATA Controllers = RAID 
Advanced > AMD PBS > NVMe RAID Mode = enabled
Boot > CSM > CSM = enabled
Boot > CSM > Both Oprom Policies = UEFI

	Because you are using two NVME SSDs, there is no reason to enable Advanced > Storage > SATA Controllers = RAID, just set it to Enabled, if you are using SATA-HDs, or Disabled, if not. Or do you want to use an SATA Raid too? Oh sh*t, these SSDs are SATA! Advanced > AMD PBS > NVMe RAID Mode = Disabled And you have to use M2_1 and M2_3, because M2_2 does not support SATA. Boot > CSM > CSM = Disabled, i guess.

	I wish I had known that M2_2 does not support SATA. That was probably a big part of the problem that I was having. And yes, it's probably in a manual somewhere. I just picked up some standard Samsung 860 SSDs and will give it a go with that. I don't want to spend days fighting with my computer just to use an M.2 drive.

	OK, it is still easy to miss, but on the ASRock page for the X570 Taichi it says "8 SATA3, 2 Hyper M.2 (PCIe Gen4 x4 & SATA3), 1 Hyper M.2 (PCIe Gen4 x4)" So yes, it would have been more logical to have M2_1 and M2_2 as the optional PCIe or SATA, and M2_3 as the dedicated PCIe slot. (ASRock also needs to fix their page, as they've got the one photo labeled PCIe Gen3 x 4) I'm wondering though, more theoretically, can the two Samsung 860 SSDs now be used with the two Crucial MX500 M2 SSDs, assuming moving the one from M2_2 to M2_3, as RAID 10? Can you, once again more theoretically, do a RAID 5 with the three M2 NVMe slots? And I take it, RAID 10 is not possible with the NVMe slots, because there are only three and you'd need four? Or is it possible to do the RAID 10 with only two ssds and setting the far2 parameter?
