Mirroring will give you the best performance for small write operations. If you can get by with two disks, I’d divide each of them into two slices, s0 and s1, say. Set up an SVM mirror between d0s0 and d1s0 and use that for your root. Set up a ZFS mirror between d0s1 and d1s1 and use that for your data.
Any 3-disk configuration would be significantly more awkward and waste some space. For mirroring in your situation, I would tend to avoid hardware RAID. You won’t be maxing out the controller rates so you won’t get much benefit.
