Is having raid0 zfs pool with copies=2 datasets equals to having raid1 zfs pool?

I have a computer with 2 hdds, which I want to use for data storage. Initially I wanted to create mirrored zfs pool, but not so much data needs to be stored so safely. So, if I create zfs pool with raid0 vdev and set copies=2 on specific datasets (for example, on which I am going to store family photos or similar), will that be same as having two pools, one mirrored for more critical data, one raid0 for standard data?
