Details… but it is *still* not redundant, so I fail to see how it
has suddenly become a RAID level. ;)

Use mdadm for a RAID1 and LVM on top by default.
Use mdadm for a RAID5 or RAID6 and LVM on top for the remaining
cases when you need space and care less about performance.
Use LVM without RAID if you need space (and/or performance) and have
the data mirrored elsewhere. I fail to see the advantage of RAID0 in
this scenario, as LVM is more flexible.
