My question, is this a raid 1+0 or 0+1? > More info can be posted if need be. This is a RAID 10 setup. That's the good way round. For some reason these RAID setups are referred to as 'RAID 10' (striped mirrors, good) or 'RAID 0+1' (mirrored stripes, bad). No idea why one gets a '+' and the other not... Note that on-board ATA Raid is often pretty simplistic. It's basically a software RAID setup without any benefit of hardware acceleration. There's no real benefit to using it over using gmirror(8), and typically a fairly big lack of support for hot swapping drives or resync'ing the mirror without taking the system down, all of which you do get with gmirror(8).
