Are modern motherboard RAID controllers hardware or software based?

Hello,

I am planning on building a new computer soon, and I am going to use two 1TB HDDs in RAID 1 for some basic protection against a hard drive failure. I have been doing some research into RAID and have found that hardware RAID solutions are superior to software RAID, and while the motherboard that I am getting (like basically all motherboards nowadays) has RAID support, I can't find any evidence as to whether or not the motherboard has a dedicated chip for the RAID, or if it's a function of the BIOS, and I should go about buying a cheap PCI RAID controller.

I'm getting a GIGABYTE GA-Z97MX-Gaming 5 in-case my question is specific to the model, but (correct me if I'm wrong), I'm assuming that I can safely generalize my question to all motherboards on the market right now.

Thanks!

Someone else may know more than me, but I think things have changed since many articles about RAID were written. If the RAID is built in to your motherboard, it is software raid, but that doesn't make it bad. Modern CPUs can actually handle the IO of a single user without any trouble. A cheap PCI RAID controller will probably have worse performance. If you want an actual RAID card, you need something with built-in RAM and either a battery or a large capacitor.
