what about raid0 with all of this lane business? it seems like raid is more trouble than its worth now. (gone the way of SLI)

Appreciate help / confirmation on this; here's my plan.. if it'll work (i9-11900k / Z590 FTW, hopefully Z590 Dark eventually): - Single GPU in PCIe 1 slot, which will run 16 lanes @ PCIe 4.0.
- Samsung 980 pro NVMe in the first m.2 slot (o/s), which will run 4 lanes @ PCIe 4.0.
- Skip the second m.2 slot so as not to mess with SATA 0 & 1.
- Samsung 970 pro NVMe in the third m.2 slot (games), which will run whatever number of lanes from the chipset @ PCIe 3.0.
- I'll very likely disable WiFi and bluetooth, if that's relevant.
Now here's where I'm unsure. I have 2 x 860 EVO SSD (for data) that I'd like to run as RAID1 (so one is just a mirror of the other).. can that be done? Do I need to use specific SATA ports for that? I've never run a RAID setup before so I'm a total newb to it. EDIT: I read through the Z590 manual on RAID, seems fairly straight forward whether I do it through the BIOS or through IRST.

right i know you can do it..... and I know how to do it..... The question is: is it worth it?
I bet the super fast M.2s run worse in RAID0 than they would running alone.... especially with this CPU/Chipset lane business.

Sorry! I thought you had both questions. I don't know how to answer that one lol. I've seen some people report that they've gotten a lot of speed out of M.2's running them in raid configurations, but I don't know exactly how or if they were correct lol. It is something I do not have experience in so I can't really answer that one.

it would seem that if you were running raid you would want both drives on the same lanes but maybe not. I can experiment i suppose.

Yeah the manual covered most of what I needed to know about RAID, seems fairly straight forward whether I do it through the BIOS or through IRST, and it appears it doesn't really matter which SATA ports I use, plus all ports retain full AHCI functionality in RAID mode, so no worries. Questions: - Is there a preferred method to use (BIOS or IRST)?
- Can I configure RAID1 with data already on one of the drives, or do I need to start with 2 formatted drives and then add data once the RAID1 is set up?

i always did it in BIOS if i was going to install the OS there.... it used to be that IRST didn't kick in until system was loaded but I am not sure anymore. I go back to the 15k RMP raptor drives in raid and the floppy disks and that whole mess.

Thanks. Heh yeah, I thought it was so special having a 160GB and then a 300GB 15k rpm Velociraptor drive back then. :)

I've always preferred to create a RAID through BIOS. IRST in Windows may be fine if you expect to transfer the drives between different systems. Generally speaking, it's always best to completely clean your drives/format them before putting them in RAID. If you want to partition the drives and create the RAID using less than the maximum for each drive to preserve the data on a partition, you can do that too. However, it's not a good idea to just setup a drive in RAID without clearing the data that will ultimately be in the logical drive (I once accidentally setup a RAID that way...it was bizarre).

Ok thanks, I'll use the BIOS method and secure erase them both first.
