Hi OrbitIf you consider yourself a newbie and is after a NAS, you probably want to go for Synology. My experience is that their software is easier to understand and work with.
And remember, RAID is not the same as backup.
What do you mean that 'RAID is not a backup'? You are going to confuse him by saying that. Please explain what you mean by that to him. You are assuming he has your frame of reference.
