ZFS currently does not have native encryption on either Linux or FreeBSD, but it is coming soon. Currently both OSs need to use some form of block level encryption either on top of, or beneath, ZFS. In Linux's case it is LUKS, and FreeBSD it is GELI. Also ZFS handles RAID better than MDADM. Whenever using ZFS and RAID, you should let ZFS handle it natively.

Probably what I would do for an encrypted ZFS RAID is this or similar (at least until native ZFS encryption is available)

Disk_1 Disk_2 Disk_3 Disk_4

Alternatively you could pool everything into a single zpool, then make an encrypted dataset on top of the Zpool.
