If you can afford either, I would personally recommend 4 low cost
drives in RAID 1. Since the drives are mirror, recovery is
straightforward and risk free. You could even put them in removable
enclosures and do backup simply by swapping out one drive of each
array.
Try to get drives from different manufacturers. You don't want to face
the kind of nightmares some of us had when/if there was a batch/model
problem, RAID can't help if all your drives brick or fail at the same
time due to the same problem.
