I set up all my devices below RAID1 if they are supported. This decreases the disk size below in half, but your devices will handle one drive that fails. If that ever happens, just replaced the drive and it will rebuild itself. You can always change back to the default RAID, and double your disk size.
NOTE: The pictures go in the same order as the list below

I will be adding more devices to this ad in the coming days.
See "seller" link top/bottom by the map depending on your device, for other items I've started to post. Will be adding more in the coming week.
