This is better than their previous POD though, which had two PSUs, but no redundancy. I.e, if a single PSU failed, the entire machine would go down as it wouldn't have enough power to run all of the drives. Obviously, for them it is cheaper to live without PSU redundancy because it is a normal day for them to lose disks and PODs because they've got so many of them, and they designed for this scenario.
