WD EX4 Raid choice

[prk72]

I just received my WD EX4 with four 4TB WD Black drives. I'm using this to store all my movies and photos on. It will be the primary source and not a backup. I'm asking for recommendations on which RAID is right for me. I've done a bit of reading, but I rather hear someone else's opinion on my specific usage and not relay on what I believe to be correct.

Do you have a means to back it up?

I do have an external seagate 4TB drive that I can incorporate into the picture.

RAID 1 over 2 drives and backup with the other 2 drives also in RAID 1 or RAID 5? I've read some say RAID 5 isn't wise with the black drives, but I've also read it isn't an issue and is fully supported. If I had Red drives I believe I would just go with RAID 5.
