I would like to RAID two of my disks, and I was wondering if the recommendation is to do software or hardware RAID?
Don't even consider hardware RAID solutions that became out-of-favour 25 years ago. You can easily do it with LVM/MDR combinations, but its more complicated and slower than the BTRFS solution, especially when rebuilding onto a new drive. Instead, because the normal Fedora installer is a bit brain-dead, unplug one of the drives and use the Fedora-default BTRFS setup. Then plug in the second drive back again, reboot and set up a RAID-1 configuration. See http://www.beginninglinux.com/btrfs for a quick tutorial. There is also a good reference guide on kernel.org, at https://btrfs.wiki.kernel.org/index.php/Using_Btrfs_with_Multiple_Devices to see what can be done. BTRFS is massively faster and safer than all other implementations other than perhaps ZFS, is at least partially error compensating, does not demand identical drives, and can be easily converted into other RAID classes dynamically as desired.
