I have two SSDs set up in RAID 1 (mirrored) as boot drives for my Proxmox server. I'm planning to change the motherboard and want to stop mirroring the drives since one of them could serve better as a backup or cache drive. I'm wondering if I can just install the new motherboard without setting up any RAID settings and boot from one of the drives. Will the system recognize that these drives were part of a RAID array and create any problems?

It really depends on how you've set up your RAID. Are you using a RAID card, motherboard RAID, or software RAID? If it's motherboard RAID, it might not be a big deal, but hardware RAID can complicate things when you switch motherboards.
If you're using hardware RAID, your data will become inaccessible when you change the motherboard. You should break the RAID configuration properly first. After that, make sure to switch to AHCI mode in the BIOS; then you can boot from one drive. Alternatively, since you’re on Linux, you could always use Clonezilla to image your installation and restore it to just one drive—it's pretty reliable!
How exactly do I break the RAID? Is it done through BIOS settings?
