I am planning on installing Arch Linux alongside Windows 10. My boot drive is a NVMe SSD but the drives I want to setup up in a RAID 1 array are my data drives (2 1TB HDDs). I was planning on using the MSI RAID settings in the BIOS but I read online that this is not advisable. Since I will only use these drives on Linux. Should I setup the RAID array during installation of Arch Linux? Also, I will be putting /opt, /var and /home directories on this RAID array, so do I setup the RAID array before setting up the partitions?

If the firmware is providing fakeraid then software raid generally has better support.

Yes the mount points you want to use contain files managed by pacman.
Also, I will be putting /opt, /var and /home directories on this RAID array, so do I setup the RAID array before setting up the partitions?
You can do either. Formatting both disks with three identical sets of partitions and creating three RAID 1 volumes then formatting those.
Alternatively create one RAID 1 volume, create three partitions on that then format those.

Why?
I'd put everything in a / partition on the SSD and then just use the RAID for my data files symlinked into ~.
If the RAID is going to be Linux only then I'd use plain mdadm instead of mobo-specific FakeRAID every time.

The space on the SSD is 200GB. As much as that is for /usr, /opt etc., I would like to be able to store a lot of programs and since /var increases as programs get updated (unless you clear it which I'd rather not do), I'd prefer to move /var to the RAID 1 array which has more space along with /opt and /home. Thanks for the suggestion, I have decided to use mdadm for the RAID array.

Just to close out the thread for people interested in this, I ended up using mdadm for RAID 1 and created the RAID array before creating the partitions.
