I wouldn't use the MOBO fakeraid. I'm not a fan of those setups at all.
But having said that how big are the drives? And are they being created
as MBR or GPT drives? I have given up trying to use anything bigger that
2TB for a boot drive in a RAID1 array. Also I have given up trying to
use GPT for those boot RAID1 arrays, installing those as the old
MSDOS/Intel MBR type, reserving the 3TB drives and GPT for RAID5 and
RAID6 configurations. It's more work to go through doing Linux software
RAID but if you have the processor speed and RAM I think that you'll be
better off in the long run with that approach. Plus if (when) something
happens to this MOBO you won't be wondering what will happen when you
put those drives into another MOBO. The Linux software RAID will migrate
forward without any potential hardware issues.
